Overview
Simultaneously measuring δ 13C, δ 18O and 12CO2, 13CO2, CO18O, CO2, and H2O concentrations.
Product Details
Carbon dioxide isotope analyzeryesLGR(Currently under ABB Canada)to2010Products launched in the year, capable of measuring simultaneouslyδ13C, δ18Oand12CO2,13CO2, CO18O, CO2as well asH2OConcentration. It can be measured continuously in situ or manually injected intermittently, and is insensitive to interference from hydrocarbons such as methane,δ13C, δ18OThe data is not affected by rapid changes in carbon dioxide concentration in the field, making it suitable for laboratory and field use and meeting various requirements for various purposesCO2Isotope measurement equipment. Recently, many researchers have developed this deviceCombining with traditional equipment to develop many new measurement methods has become a promising new direction.
characteristic:
1. Simultaneous measurementδ13C，δ18O，CO2Concentration andH2Oconcentration
2. Wide range,CO2The concentration range is380~25000 ppm
3. 1 HzHigh frequency measurement
4. Ultra stable measurement, high precision and accuracy, minimal drift
5. Combination of in-situ continuous measurement and manual intermittent injection
6. Synchronous measurementCO2Isotope molecules, isotope ratios are not affectedCO2The impact of rapid changes in concentration
