Definition		Graphite furnace atomic absorption spectrometry (GF-AAS) (also known as Electrothermal Atomic Absorption Spectrometry (ET-AAS)) is a type of spectrometry that uses a graphite-coated furnace to vaporize the sample. Briefly, the technique is based on the fact that free atoms will absorb light at frequencies or wavelengths characteristic of the element of interest (hence the name atomic absorption spectrometry). Within certain limits, the amount of light absorbed can be linearly correlated to the concentration of analyte present. Free atoms of most elements can be produced from samples by the application of high temperatures. Source: http://en.wikipedia.org/wiki/Graphite_furnace_atomic_absorption

Definition		High-performance liquid chromatography (sometimes referred to as high-pressure liquid chromatography), HPLC, is a chromatographic technique used to separate a mixture of compounds in analytical chemistry and biochemistry with the purpose of identifying, quantifying and purifying the individual components of the mixture. HPLC-FLD is done with fluorescence detection.

Definition		High performance liquid chromatography–mass spectrometry (HPLC-MS, or alternatively LC-MS) is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry. LC-MS is a powerful technique used for many applications which has very high sensitivity and selectivity. Generally its application is oriented towards the general detection and potential identification of chemicals in the presence of other chemicals (in a complex mixture). The limitations of LC-MS in urine analysis drug screening is that it often fails to distinguish between specific metabolites, in particular with hydrocodone and its metabolites.

Definition		When a continuum radiation source is used for AAS measurement it is indispensable to work with a high-resolution monochromator. The resolution has to be equal to or better than the half width of an atomic absorption line (about 2 pm) in order to avoid losses of sensitivity and linearity of the calibration graph. These spectrometers use a compact double monochromator with a prism pre-monochromator and an echelle grating monochromator for high resolution. A linear charge coupled device (CCD) array with 200 pixels is used as the detector. The second monochromator does not have an exit slit; hence the spectral environment at both sides of the analytical line becomes visible at high resolution. As typically only 3–5 pixels are used to measure the atomic absorption, the other pixels are available for correction purposes. One of these corrections is that for lamp flicker noise, which is independent of wavelength, resulting in measurements with very low noise level; other corrections are those for background absorption, as will be discussed later.

Definition		Ion chromatography (or ion-exchange chromatography) is a process that allows the separation of ions and polar molecules based on their charge. It can be used for almost any kind of charged molecule including large proteins, small nucleotides and amino acids. The solution to be injected is usually called a sample, and the individually separated components are called analytes. It is often used in protein purification, water analysis, and quality control.

Definition		Inductively coupled plasma atomic emission spectroscopy (ICP-AES), also referred to as inductively coupled plasma optical emission spectrometry (ICP-OES), is an analytical technique used for the detection of trace metals. It is a type of emission spectroscopy that uses the inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element.[1][2] The intensity of this emission is indicative of the concentration of the element within the sample.

Definition		Inductively coupled plasma mass spectrometry (ICP-MS) is a type of mass spectrometry which is capable of detecting metals and several non-metals at concentrations as low as one part in 1012 (part per trillion). This is achieved by ionizing the sample with inductively coupled plasma and then using a mass spectrometer to separate and quantify those ions.

Definition		Isotope dilution analysis is a technique to increase the precision and accuracy of chemical analysis. The isotopic composition of the sample will be slightly changed. Then, by measuring each isotope, the amount of a single element/pollutant in the original sample can be calculated. In a typical gas chromatography analysis, isotopic dilution can decrease the error of injection from 5% to 1%. It can also be used in mass spectrometry (commonly referred to as isotopic dilution mass spectrometry or IDMS), in which the isotopic ratio can be determined with precision typically better than 0.25%.

Definition		Isotope-ratio mass spectrometry (IRMS) is a spectroscopic analysis method used to determine the ratio of different isotopes within a sample. IRMS can help establish the sample's isotope fingerprint, which gives it applications in evaluating the authenticity and geographical origin of products and materials.

Definition		The extracted samples are analyzed for ammonium on the high sensitivity AMFIA (AMmonia Flow Injection Analysis) system, which is an automated system developed at ECN, Petten, NL (Wyers et al. 1993). AMFIA is based on the selective dialysis of ammonia across a membrane at high pH with subsequent analysis of conductivity.

Definition		Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. It is more specific than the general term electromagnetic spectroscopy in that spectrophotometry deals with visible light, near-ultraviolet, and near-infrared, but does not cover time-resolved spectroscopic techniques. Spectrophotometry involves the use of a spectrophotometer. A spectrophotometer is a photometer that can measure intensity as a function of the light source wavelength. Important features of spectrophotometers are spectral bandwidth and linear range of absorption or reflectance measurement.

CSV Import

The CSV file should contain a header row for element names and data rows for concepts.
It is strongly recommended to use an exported CSV file as a template for bulk editing. Columns and rows can be added to or deleted from the template file.
A concept can be ignored by prepending a double-slash '//' to the concept row in the CSV

If the header row contains unknown elements the import will aborted and data will be rolled back
Erroneous concept rows are ignored, valid data rows are still imported
Successful import cannot be undone (unless "undo checkout" is performed)
If a concept with the same identifier already exists in the vocabulary it will be overwritten
"Purge Vocabulary" option deletes all the vocabulary concepts before import
