What is GC-MS

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

Mass spectrometers significantly expand the capabilities of gas chromatographs, making it possible to identify components not only by retention times, but also by mass spectra. The company produces mass spectrometers of various geometries:
Quadrupole mass spectrometers are designed to solve most routine analytical tasks.
Three-quadrupole mass spectrometers are designed for the analysis of trace contents of components in complex matrices.
 Magnetic sector and time-of-flight mass spectrometers are designed for high resolution analysis for special applications.
