FIA – Flow Injection Analysis
#
- microchemical technique to automate wet chemical methods. In a FIA system, a carrier solution and the chemical reagents are continuously pumped through tubes, mixing coils and finally through a flow cell in a detector. A small portion of the sample is injected into the carrier. The carrier merges with one or more reagents to produce a chemical reaction. The resulting colour change in the sample zone is measured in the detector. The time between injection and detection is typically 1 minute. The dispersion or dilution of the sample zone is controlled by the system components, i.e. injected volume, flow rates and length and diameter of the tubing. When the dispersed sample zone reaches the flow cell of the detector neither the chemical reaction nor the dispersion process must have reached completion or a steady state. Keeping identical conditions for both samples and standards makes evaluation and quantification reproducible and precise. www.foss.dk

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

-
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/

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

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

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

FIA – Flow Injection Analysis
#
- microchemical technique to automate wet chemical methods. In a FIA system, a carrier solution and the chemical reagents are continuously pumped through tubes, mixing coils and finally through a flow cell in a detector. A small portion of the sample is injected into the carrier. The carrier merges with one or more reagents to produce a chemical reaction. The resulting colour change in the sample zone is measured in the detector. The time between injection and detection is typically 1 minute. The dispersion or dilution of the sample zone is controlled by the system components, i.e. injected volume, flow rates and length and diameter of the tubing. When the dispersed sample zone reaches the flow cell of the detector neither the chemical reaction nor the dispersion process must have reached completion or a steady state. Keeping identical conditions for both samples and standards makes evaluation and quantification reproducible and precise. www.foss.dk

TCD - Thermal conductivity detector
#
- A number of detectors are used in gas chromatography. The most common are the flame ionization detector (FID) and the thermal conductivity detector (TCD). Both are sensitive to a wide range of components, and both work over a wide range of concentrations. While TCDs are essentially universal and can be used to detect any component other than the carrier gas (as long as their thermal conductivities are different from that of the carrier gas, at detector temperature), FIDs are sensitive primarily to hydrocarbons, and are more sensitive to them than TCD. However, an FID cannot detect water. Both detectors are also quite robust. Since TCD is non-destructive, it can be operated in-series before an FID (destructive), thus providing complementary detection of the same analytes. en.wikipedia.org

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

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/

By using smaller particles, speed and peak capacity (number of peaks resolved per unit time in gradient separations) can be extended to new limits, termed Ultra Performance Liquid Chromatography, or UPLC. The technology takes full advantage of chromatographic principles to run separations using columns packed with smaller particles and/or higher flow rates for increased speed, with superior resolution and sensitivity. www.lcgcmag.com

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

Western blot test
#
- A technique in which protein is transferred from an electrophoretic gel to a cellulose or nylon support membrane following electrophoresis. A particular protein molecule can then be identified by probing the blot with a radiolabelled antibody which binds only the specific protein to which the antibody was prepared. Useful, for example, for measurement of levels of production of a specific protein in a particular tissue or at particular developmental stage. www.fao.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

Alpha Testing
#
- (i) Testing conducted internally by the manufacturer, alpha testing takes a new product through a protocol of testing procedures to verify product functionality and capability. www.wrightcolorgraphics.com (ii) In-house testing of a software product. www.eabnet.org.uk
-
Beta testing
#
- (i) testing conducted at one or more customer sites by the end-user of a delivered software product or system. This is usually a "friendly" user and the testing is conducted before general release for distribution. www.stsc.hill.af.mil (ii) User testing of a completed information system using real data in the real user environment. www.cbu.edu

Beta version
#
- (i) a product in that is in its final stages of testing. Often, especially with FOSS, a beta version of a product (or beta product), will be made available to the public for general use and may contain minor bugs. This is done so that the product can be tested on a large-scale in the field, and allow people to start using new tools as soon as possible. www.cpsr-peru.org (ii) In software engineering, development stage terminology expresses how the development of a piece of software has progressed and how much further development it may require. Each major version of a product usually goes through a stage when new features are added (alpha stage), then a stage when it is actively debugged (beta stage), and finally a stage when all important bugs have been removed (stable stage). Intermediate stages may also be recognized. en.wikipedia.org

PERT - Program Evaluation and Review Technique
#
- a project management technique for determining how much time a project needs before it is completed. each activity is assigned a best, worst, and most probable completion time estimate. These estimates are used to determine the average completion time. The average times are used to figure the critical path and the standard deviation of completion times for the entire project. cio.osu.edu

RBS - Resource Breakdown Structure
#
- in project management, the Resource Breakdown Structure (RBS) is a standardized list of personnel resources related by function and arranged in a hierarchical structure. The Resource Breakdown Structure standardizes the Departments personnel resources to facilitate planning and controlling of project work. It defines assignable resources such as personnel, from a functional point of view; it identifies "who" is doing the work. The total resources define the Top Level, and each subsequent level is a subset of the resource category (or level) above it. Each descending (lower) level represents an increasingly detailed description of the resource until small enough to be used in conjunction with the Work Breakdown Structure (WBS) to allow the work to be planned, monitored and controlled. en.wikipedia.org

Risk
#
- the cumulative effect of the chances of uncertain occurrences, which will adversely affect project objectives. It is the degree of exposure to negative events and their probable consequences. Project risk is characterized by three risk factors namely: risk event, risk probability and the amount at stake. Risk is the opposite of opportunity. cio.osu.edu

Scope creep
#
- (i) the tendency of a project to include more tasks or to implement more systems than originally specified, which often leads to higher than planned project costs and an extension of the initial implementation date. bridgefieldgroup.com. (ii) Scope creep is the slow and continuous expansion of the scope or a project, such as data type or routine, resulting in a broad, unfocused, and unmanageable scope and usually leads to cost-overruns, missed deadlines, and loss of original goals. www.tjiss.net
