The combination of elemental analysis (EA) with isotope ratio mass spectrometry (IRMS) has allowed the explosion of stable isotope analysis across a broad range of application areas. EA-IRMS is an important technique used to measure the percentage of C, H, N, O, S elements in the sample and the stable isotope ¹³C, ¹⁵N content. The analysis of the non-metallic elements like C, N, H, O, S can deliver powerful insight into many scientific questions.

Applications

Determining the elemental composition and isotopic ratio in different types of samples, including chemicals, soil and sediment, plant, food and drinks, fuel. Widely used in soil science, botany, environmental science, oceanography, lake biology and the identification of food and medicine.
