Definition		The instrument's primary operating mechanism is the radiometric microbalance system, which relies on changes in the strength of a beta ray beam passing through the filter paper to determine changes in particulate mass collected. A Beta Attenuation Monitor is comprised of three main components: the PM air inlet, the central instrument, and the vacuum pump.

Definition		Cold vapour atomic fluorescence spectroscopy is a subset of the analytical technique known as atomic fluorescence spectroscopy (AFS). Used in the measurement of trace amounts of volatile heavy metals such as mercury, cold vapour AFS makes use of the unique characteristic of mercury that allows vapour measurement at room temperature. Free mercury atoms in a carrier gas are excited by a collimated ultraviolet light source at a wavelength of 253.7 nanometres. The excited atoms re-radiate their absorbed energy (fluoresce) at this same wavelength.

Definition		In atmospheric chemistry, differential optical absorption spectroscopy (DOAS) is used to measure concentrations of trace gases. When combined with basic optical spectrometers such as prisms or diffraction gratings and automated, ground-based observation platforms, what we have is a cheap and powerful means for the measurement of such trace gas species as ozone and nitrogen dioxide.

Definition		A flame ionization detector (FID) is a type of gas detector used in gas chromatography. The detection of organic compounds is most effectively done with flame ionization.

Definition		Gas chromatography–mass spectrometry (GC-MS) is a method that combines the features of gas-liquid chromatography and mass spectrometry to identify different substances within a test sample.

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		A nondispersive infrared sensor (or NDIR) sensor is a simple spectroscopic device often used as gas detector. The main components are an infrared source (lamp), a sample chamber or light tube, a wavelength sample chamber, and gas concentration is measured electro-optically by its absorption of a specific wavelength in the infrared (IR). The IR light is directed through the sample chamber towards the detector. In parallel there is another chamber with an enclosed reference gas, typically nitrogen. The detector has an optical filter in front of it that eliminates all light except the wavelength that the selected gas molecules can absorb.

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.

Definition		A continuous direct mass measurement particulate matter utilizing a tapered element oscillating microbalance (TEOM) and correction with estimated volatile fraction (A correction to take into account the missing volatile fraction. This fraction is estimated from another station where a TEOM 1400 and a TEOM FDMS are used in parallel.)

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
