Gas Chromatography-Mass Spectrometry (Thermo Trace DSQ)

Gas Chromatography-Mass Spectrometry (Thermo Trace DSQ)

ography-Mass Spectrometry (Thermo Trace DSQ)

 

 This source and detector combination allows detection of smaller concentrations of compounds in difficult matrices, which has made up the deficiency on qualitative analysis of gas chromatography. At the same time, the direct sample probe provides an alternate means of sample introduction that reduces or eliminates sample preparation time. The technique requires a minimal sample amount for testing.
