Instrument used to identify and quantify volatile chemicals in a sample by a gas phase separation technique. After being separated on the chromatographic column, sample components pass through a detector (e.g., see FID and ECD) that creates an electric signal proportional to the concentration of sample components in the carrier gas stream. Also referred to as a GC.
A laboratory instrument used to separate and analyse chemicals in a sample. Go to http://en.wikipedia.org/wiki/Gas_chromatography to find out more.
is an instrument for the analysis of organic chemical mixtures. In a spiral ass or metal column, packed with porous material, the various components are separated according to physical properties such as polarity ad vapor pressure. The signals received are amplified and, with the help of a printer, printed onto a chromatogram.
a device containing a computer system for the analysis of blood samples for blood-alcohol concentration. This is the most common method of analysis.
an instrument utilized to perform an analytical method that is used for the separation, identification and determination of chemical components in a complex mixture.
An analytical instrument used for separating the various components of a gas mixture, and measuring the relative concentrations of each. These instruments are used routinely by mud logging contractors to identify the types of hydrocarbons encountered in the drilling process. See partition gas chromatograph.
