World's first simultaneous 13C+D isotope analyzer
Picarro B2221-i Analyzer
Perform simultaneous carbon-13 and deuterium isotope analysis for bulk organic samples.
- Combust one sample to measure both 13C + D ratios
- One analyzer replaces two IRMS systems
- Comparable precision to IRMS at one-third the upfront investment
- Much faster than IRMS—20 minutes per replicate for both 13C+D analyses
- Easy sample prep. 99 replicates run in 33 hours while unattended
With high precision, unprecedented ease of use, unparalleled speed and low cost of ownership, the B2221-i Analyzer is an accessible, practical alternative to mass spectrometry.
Traditionally, measuring carbon and hydrogen isotope ratios requires two separate isotope ratio mass spectrometry (IRMS) techniques (EA-IRMS for 13C/12C and TC/EA-IRMS for D/H). IRMS measurements are not made simultaneously and thus require separate sample preparation and instrument set-up by a highly trained operator. The Picarro 13C + D Analyzer supplants both IRMS techniques, enabling any person of moderate technical capability to perform world-class isotope analyses. Our 13C + D Analyzer is so simple that it can be deployed in the field.
How does it work? A liquid or solid organic sample is wrapped in tin foil and placed in the autosampler. Then the sample is combusted within the reaction column of the combustion module, converting all the carbon to CO2 and all the hydrogen to H2O. These combustion products flow into the state-of-the-art Picarro analyzer, which measures the 13C/12C ratio in CO2 and the D/H ratio in H2O, simultaneously reflecting the ratios in the original bulk organic sample. Unlike IRMS, the B2221-i uses N2 as a carrier gas, which is far cheaper than helium. It also does not require pulses of CO2 and H2 reference gases of known isotope ratio.
The analyzer combines Picarro’s high-precision isotopic CRDS with combustion technology to produce an instrument ideally suited for a wide range of 13C + D bulk stable isotope analysis applications. Expand the use of stable isotope techniques into new scientific applications and research initiatives. Read more about 13C + D applications in Nabil Saad's blog.
