How Does Irms Work?

IRMS measurements yield the information of isotopic ratio

of the analyte gas relative to the measured isotope ratio of a reference gas. This is done to compensate for mass discrimination effects that may fluctuate with time and from instrument to instrument.

What is the use of IRMS?

Isotope ratio mass spectrometry (IRMS) is a technique used to measure the relative abundance of isotopes in materials. Forensic investigators have used IRMS to measure a variety of materials, such as drugs, explosives, food, and human remains.

What is IRMS analysis?

Isotope-ratio mass spectrometry (IRMS) is a specialization of mass spectrometry, in which mass spectrometric methods are used to measure the relative abundance of isotopes in a given sample. This technique has two different applications in the earth and environmental sciences.
