Elemental Analysis by Sercon
ELEMENTAL ANALYSIS SYSTEMS
EA-IRMS (Elemental Analysis-Isotope Ratio Mass Spectrometry) is an analytical technique used to measure the bulk stable isotope ratios of elements (e.g., carbon, nitrogen, oxygen) in a sample. It involves the combustion or pyrolysis of the sample to convert it into simple gases (CO2, N2, SO2, etc.), which are then analysed by IRMS to determine the isotopic composition. This established technique is widely used in fields like ecology, geology, and food authenticity to track and study natural processes and origins.
Sercon EA instruments are built on decades of EA-IRMS innovation, tracing their heritage back to Europa Scientific’s groundbreaking Roboprep, the first commercially available system. The Sercon IsoEArth systems are advanced elemental analysers, expertly designed for seamless integration with IRMS instruments. When paired with the high sensitivity of the HS2022 IRMS, the isoEArth provides precise and accurate elemental and isotopic data.
