Ultimate compound separation and identification technology for complex mixture analysis—delivering unparalleled analytical certainty with definitive compound identification.
The gold standard analytical technique providing complete compound separation and definitive identification for complex mixture analysis.
Gas Chromatography (GC) is the gold standard analytical technique for separating, identifying, and quantifying volatile and semi-volatile compounds. The method uses a mobile gas phase (carrier gas) to transport sample components through a stationary phase (column) where compounds are separated based on their chemical properties.
Each compound exhibits a unique retention time on the column, enabling precise identification and quantification. When combined with advanced detectors like mass spectrometry (GC-MS), this technology provides unparalleled analytical certainty.
