Organisations often purchase software from different vendors in order to obtain the best-of-breed for each application area; for example, a human resources package from one vendor and an accounting package from another. While enterprise solution (ERP) vendors provide a wealth of applications for the enterprise and tout their integrated system as the superior solution, every module may not be best-of-breed. It is difficult to excel in every niche. www.answers.com
Bilirubin #
a chemical breakdown product of hemoglobin. Hemoglobin is a substance in red blood cells that grabs onto oxygen in the lungs and carries it to the tissues in the body where it releases it. When red blood cells wear out they are trapped in the spleen and destroyed, releasing bilirubin into the blood. This type of bilirubin is called unconjugated. The liver takes the bilirubin out of the blood and conjugates it by attaching a portion of another molecule to the bilirubin molecule. www.classkids.org
BOD - Biochemical Oxygen Demand #
A measure of the amount of oxygen consumed in the biological processes that break down organic matter in water. BOD is used as an indirect measure of the concentration of biologically degradable material present in organic wastes. It usually reflects the amount of oxygen consumed in five days by biological processes breaking down organic waste. BOD can also be used as an indicator of pollutant level, where the greater the BOD, the greater the degree of pollution. antron.dupont.com

Creatinine is removed from the body by the kidneys; as kidney disease progresses, the level of creatinine in the blood increases. www.diabetes.org. a substance in the blood (a piece of a protein) which should be at a constant level in the blood. When creatinine levels rise in the blood, it can be a sign that the kidneys are not functioning well. Sometimes, creatinine is measured in the blood and in the urine, as part of a Creatinine Clearance test. www.abcbirth.com
CSF - Cerebrospinal Fluid #
a clear, colourless fluid that contains small quantities of glucose and protein. Cerebrospinal fluid fills the ventricles of the brain and the central canal of the spinal cord.

Mycotoxin #
Certain molds, such as Aspergillus, Fusarium, Penicillium, Chaetomium and Stachybotrys release chemicals during their metabolic cycle called mycotoxins, which can be toxic to humans and animals. These chemicals can be found in the mold spores, within the mold itself, and in the materials that the mold is growing. Inhalation of mold spores or dust containing mycotoxins can result in human exposure with potentially severe heath effects. www.totalwellness.com
NTU - Nephelometric Turbidity Unit #
The unit used to describe turbidity. Nephelometric refers to the way the instrument, a nephelometer, measures how much light is scattered by suspended particles in the water. The greater the scattering, the higher the turbidity. Therefore, low NTU values indicate high water clarity, while high NTU values indicate low water clarity. www.pca.state.mn.us
OSS · Open Source Software #

Proprietary Software #
i) is software offered for sale or license where the vendor controls the source code. www.dis.wa.gov ii) Much of the software users are accustomed to is known as proprietary software. With proprietary software users are not allowed to see the source code. Nor are they able to modify the code for their own use or to distribute to others. In some cases certain customers are allowed to view the source code - sometimes for an additional fee - but even then they are not able to alter and re-distribute the software. Examples of proprietary software include Microsoft's Office suite. floss.meraka.org.za
QA - Quality Assurance #

SaaS - Software as a Service #
(i) a software application delivery model where a software vendor develops a web-native software application and hosts and operates the application for use by its customers over the Internet. Customers pay not for owning the software itself but for using it. The term SaaS has become the industry preferred term, generally replacing the earlier terms Application Service Provider (ASP), On-Demand and "Utility computing" (ii) As a term, SaaS is generally associated with business software and is typically thought of as a low-cost way for businesses to obtain the same benefits of commercially licensed, internally operated software without the associated complexity and high initial cost. Consumer-oriented web-native software is generally known as Web 2.0 and not as SaaS. Many types of software are well suited to the SaaS model, where customers may have little interest or capability in software deployment, but do have substantial computing needs. Application areas such as Customer Relations Management, Video Conferencing, Human Resources, Accounting and Email are just a few of the initial markets showing SaaS success. The distinction between SaaS and earlier applications delivered over the Internet is that SaaS solutions were developed specifically to leverage web technologies such as the browser, thereby making them web-native. www.beingpro.com

Instruments

AES - Auger Electron Spectroscopy #
Auger (pronounced ~o-jay) electron spectroscopy is an electron spectroscopic method that uses a beam of electrons to knock electrons out of inner-shell orbitals. Auger electrons are ejected to conserve energy when electrons in higher shells fill the vacancy in the inner shell. These Auger electrons have energies characteristic of the emitting atom due to the characteristic energy-level structure of that element. elchem.kaist.ac.kr
Autoclave #
Closed vessel for conducting chemical reactions under high pressure and temperature www.potterseurope.org. a device that uses steam to sterilise equipment and other objects. This means that all bacteria, viruses, fungi, and spores are inactivated. However, in 2003 scientists discovered a single-cell organism, Strain 121, that survives autoclave temperatures. Prions also may not be destroyed by autoclaving. en.wikipedia.org
Cryoscope #
a measuring instrument for measuring freezing and melting points. wordnet.princeton.edu
FID - Flame Ionization Detector #
a type of detector used in gas chromatography. See GC FID. The Flame Ionization Detector (FID) is one of the many methods by which to analyze materials coming off of gas chromatography column. The detection of organic compounds is most effectively done with flame ionization. Biochemical compounds such as proteins, nucleotides, and pharmaceuticals can be studied with flame ionization as well as other detectors, like thermal conductivity, thermionic, or electrolytic conductivity due to the presence of nitrogen, phosphorus, or sulfur atoms or because of the universality of the thermal conductivity detector. However, typically the biochemical compounds have a greater amount of carbon present than other elements. This means that a particular compound may be more easily detected using flame ionization over the other methods because of higher carbon concentration and also flame ionizations sensitivity. http://en.wikipedia.org
FOSS · Free Open Source Software #
Also see glossary item OSS (i) a joint term sometimes used when refering to the Free Software and Open Source communities as a whole without differentiating between the terms and the matching philosophies. www.libervis.com (ii) an acronym that is most often used in English-speaking military software communities.The acronym was first used in a 2003 MITRE report that documented widespread use of, and reliance on, free software and open source software in the United States Department of Defense. www.wikipedia.org
GC - Gas chromatography #
a method for separating substances in a mixture and measuring the relative quantities of substances. It is a useful technique for substances that do not decompose at high temperatures and when a very small quantity of sample is available. www.polymicro.com
GC FID - Gas Chromatograph(y) Flame Ionization Detector #
n GC/FID, the FID or flame ionization detector detects analytes by measuring an electrical current generated by electrons from burning carbon particles in the sample. The flame ionization detector (FID) is a non-selective detector used in conjunction with gas chromatography. Because it is non-selective, there is a potential for many non-target compounds present in samples to interfere with this analysis and for poor resolution especially in complex samples. The FID works by directing the gas phase output from the column into a hydrogen flame. A voltage of 100-200V is applied between the flame and an electrode located away from the flame. The increased current due to electrons emitted by burning carbon particles is then measured. Although the signal current is very small (the ionization efficiency is only 0.0015%) the noise level is also very small (<10-13 amp) and with a well-optimized system, sensitivities of 5 x 10-12 g/ml for n-heptane at a signal/noise ratio of 2 can be easily realized. Except for a very few organic compounds (e.g. carbon monoxide, etc.) the FID detects all carbon containing compounds. The detector also has an extremely wide linear dynamic range that extends over, at least five orders of magnitude with a response index between 0.98-1.02. http://www.chromatography-online.org/
Homogeniser #
A mechanical device which is used to create a stable, uniform dispersion of an insoluble phase within a liquid phase. www.alken-murray.com
HPLC - High Performance Liquid Chromatography #
a family of analytical chemistry techniques for the separation of mixtures. It involves passing the sample, a mixture which contains the analyte, in the "mobile phase", often in a stream of solvent, through the "stationary phase." The stationary phase retards the passage of the components of the sample. When components pass through the system at different rates they become separated in time, like runners in a marathon. ... en.wikipedia.org
Hydrometer #
An inexpensive and widely available analytical device that measures the specific gravity (relative density) of a solution. Very useful to measure the amount of sugar (in Balling or degrees Brix) in a juice or wine. Because density depends on temperature, a thermometer reading of the solution being tested is critical for accurate results. Hydrometers are calibrated to be used at 60° F. winemakermag.com
ICP - Inductively Coupled Plasma #
(i) ICP, combined with optical emission spectrometry, is a commonly used technique to determine chemical analysis of master alloys. www.metallurgaluminium.com (ii) a high temperature conductive gaseous mixture, contained and energized by a radio frequency electromagnetic field. Often used in AES (Auger Electron Spectroscopy) as a source of energy for the generation of emission spectra from elements. www.ionsigtech.com
ISE - Ion Selective Electrode #
These electrodes respond to ions present in a sample. A potential develops across the membrane surface that is selectively dependent on the concentration of one particular ion in solution. The magnitude of the potential relates to the concentration of the ion concentration. The higher the potential, the higher the concentration. www.ne-wea.org
Kjeldahl method #
a method for the quantitative determination of nitrogen in chemical substances developed by Johan Kjeldahl. The method as described in Julius Cohen's Practical Organic Chemistry of 1910 consists of heating a substance with sulfuric acid which oxidizes nitrogen to ammonium sulfate. In this step potassium sulfate is added in order to increase the boiling point of the medium from 337°C to 373°C. Chemical decomposition of the sample is complete when the medium has become clear and colorless (initially very dark). The solution is then distilled with sodium hydroxide added in small quantities, which converts the ammonium salt to ammonia. The end of the condenser is dipped into a solution of hydrochloric acid or sulfuric acid of precisely known concentration. The ammonia reacts with the acid and the remainder of the acid is then titrated with a sodium carbonate solution with a methyl orange PH indicator. In modern times the Kjeldahl method is largely automated and makes use of specific catalysts like mercury oxide or copper sulfate to speed up the decomposition. en.wikipedia.org
Lactometer #
device used to measure the specific gravity, and therefore the richness, of milk. www.answers.com
Lactoscope #
instrument measuring amount of cream in milk. www.tiscali.co.uk
Laminar flow cabinet #
A laminar flow cabinet creates a particle-free working environment by taking air through a filtration system and exhausting it across a work surface in a laminar or unidirectional air stream. Commonly, the filtration system compromises of a pre-filter and a HEPA filter. Because the air within the cabinet does not contain any airborne particles, it is also sterile. The laminar flow cabinet is enclosed on the sides and kept under constant positive pressure in order to prevent the infiltration of contaminated room air. The most common application of the laminar flow cabinet is to provide an individual clean air environment for small items not requiring a full-size cleanroom. In the laboratory, individual laminar flow cabinets are commonly used for specialized work such as spin coating to eliminate airborne contamination that would otherwise interfere with work processes. www.polymer-physics.uwaterloo.ca
LC - Liquid chromatography #
an analytical chromatographic technique that is useful for separating ions or molecules that are dissolved in a solvent. If the sample solution is in contact with a second solid or liquid phase, the different solutes will interact with the other phase to differing degrees due to differences in adsorption, ion-exchange, partitioning, or size. These differences allow the mixture components to be separated from each other by using these differences to determine the transit time of the solutes through a column. www.polymicro.com
MS · Mass spectrometer #
instrument used to measure the masses of molecules and atoms by volatilizing and then ionizing them. The ions are then separated magnetically according to their mass-to-charge ratio. www4.nau.edu

UV/Vis Spectroscopy #
Ultraviolet-visible spectroscopy or ultraviolet-visible spectrophotometry involves the spectroscopy of photons and spectrophotometry. It uses light in the visible and adjacent near ultraviolet (UV) and near infrared (NIR) ranges. http://en.wikipedia.org/wiki/UV-Visible_spectroscopy
Viscometer (viscosimeter) #
an instrument used to measure the viscosity and flow parameters of a fluid. The common Brookfield-type viscometer determines the required force for rotating a disk in the fluid at known speed. Other viscometer types use bubbles, balls or other objects. Viscometers that can measure fluids with high viscosity or molten polymers are usually called rheometer or plastometer. en.wikipedia.org
XRFS - X-Ray Fluorescence Spectroscopy #
a spectroscopic technique that is commonly used with solids, in which X-rays are used to excite a sample and generate secondary X-rays. The X-rays broadcast into the sample by X-ray fluorescence spectrometers eject inner-shell electrons. Outer-shell electrons take the place of the ejected electrons and emit photons in the process. The wavelength of the photons depends on the energy difference between the outer-shell and inner-shell electron orbitals. The amount of X-ray fluorescence is very sample dependent and quantitative analysis requires calibration with standards that are similar to the sample matrix. http://test-equipment.globalspec.com
