Gas Chromatography (“GC”) is an analytical technique used for separating liquids or gases via a capillary column using gas as the solvent medium.
This technique is used to characterize, identify, and quantitate volatile and semi-volatile components in various sample matrices. Contaminants can be determined from the percent level to part per billion (“PPB”) depending on the analyte being detected.
While the GC is a temperature controlled oven, it is the detector to which it is coupled that determines what can be seen. At Impact Analytical our scientists can use detectors such as:
By utilizing both purchased (NIST) and in-house spectral databases the scientists are able to identify unknowns.
The GC’s at Impact Analytical are qualified for testing under cGMP or GLP
(FDA, EPA) guidelines.
