GC IsoLink irm-GC/MS System

Thermo Scientific GC IsoLink integrates the TRACE GC Ultra with the gas isotope ratio mass spectrometers (DELTA V and MAT 253) into one easy-to-use unit.

 

It uses an improved combustion technology, which does not need a reduction reactor; hence reducing the number of sensitive connections in the gas flow and improving the peak performance.

Chemical and physical processes can change the natural isotope composition of organic compounds. The carbon, nitrogen, oxygen, and hydrogen isotope ratios preserve a trace to these events in every molecule of a compound. These isotope signatures reveal information not accessible in any other way. This includes the origin of a compound, its synthesis pathway, conditions at its formation, sometimes even a substrate can be discovered. Paleoclimatic and diagenetic conditions can be resolved by the compound specific isotope analysis of biomarkers.

Metabolic pathways can be unraveled by using isotopic tracers with lowest artificial isotope enrichment or with a distinctly different natural abundance.
