Integrated Elemental Analysis Stable Isotope Ratio Mass Spectrometer

1Integrated Elemental Analysis Stable Isotope Ratio Mass SpectrometerProduct Introduction

Integra2It is a subsidiary of Tianmei GroupSerconThe compact integrated elemental analysis launched-Stable isotope ratio mass spectrometer（EA-IRMS）. The core of the instrument integrates the dual functions of an element analyzer and a stable isotope ratio mass spectrometer, which can be implemented as standard¹⁵NThe¹³CSynchronous detection of stable isotopes, expandable through optional upgrade packages¹⁸OThe³⁴SIsotope analysis capability, with special optimization for sulfur element analysis, and detection precision can be better than0.3‰.

This instrument relies on120°Ionic optical structure, permanent magnet separation technology, and innovative capture circuit design, without the need for reference gas cylinders, can burn and retain reference materials through the capture circuit for instrument tuning andDeltaValue calculation avoids the storage and use risks of hazardous gases from the source. At the same time, the instrument is paired with a turbo molecular vacuum pump and a high-quality stainless steel valve system, which not only significantly reduces equipment maintenance frequency and consumables usage costs, but also achieves efficient detection¹⁵NSingle element analysis only requires4minute/sample¹⁵N+¹³CJoint analysis only requires6minute/Sample; The sample has a wide range of adaptability and is compatibleC/NContent in5-2000μgSolid and liquid samples within the interval.

With its compact and lightweight body design, this instrument can be adapted to mobile laboratories and testing vehicles/Special usage scenarios such as ships support real-time on-site detection and data acquisition, effectively avoiding the isotope fractionation effects that may occur during sample storage and transportation. It can widely meet the needs of on-site rapid detection and laboratory routine isotope analysis in fields such as environment, agriculture, and food.
