The Isotope5 CN Isotope ratio mass spectrometer is a small mass spectrum analyzer produced by the British company Compact Science Systems introduced by PRI-ECO. Isotope5 breaks many limitations of the use of mass spectrometers, is small and light, and can be placed on a laboratory desktop. The performance of isotope is stable and reliable, and high quality isotope data can be quickly measured. Simple and fast operation, no need for professional and technical personnel to run; The operation cost is economical, and only needs less helium, standard gas and electricity.
The Isotope5 CN mass spectrometer and the Element5 analyzer can be combined to form a full-performance EA-IRMS for elemental and isotope analysis of solid and liquid samples. It can be connected with gas chromatography to form a stable and reliable GC-IRMS for material content and isotope analysis of gaseous samples. It can also be connected with liquid chromatography to form fast and efficient LC-IRMS for the substance content and isotope analysis of liquid samples. Among them, EA-IRMS is equipped with Element5 analyzer, which can measure the CN content of the sample, and provide high-purity CO2 and N2 of the Isotope5 for the analysis of CN isotope. Element5 can also be used independently to measure the CNHS or O element content of a sample.
The Isotope5 CN mass spectrometer allows rapid detection of samples containing CN in application scenarios such as material cycling (e.g., CN cycling studies), food authenticity (e.g., honey adulteration), and disease diagnosis (e.g., Helicobacter pylori identification). It can help people make new discoveries in the fields of climate research, biochemistry, forensic medicine, food analysis, oil and gas exploration, and soil science.
