Picarro Combustion Module Cavity Ring Down Spectroscopy Stable Isotope Analysis

  1. 1. Combustion Module-CRDS A Unique Solution for Bulk 13 C Analysis
  2. 2. What if you could run bulk 13 C analysis… <ul><li>With high-precision </li></ul><ul><li>With unprecedented ease-of-use </li></ul><ul><li>With a compact system </li></ul><ul><li>For far cheaper than IRMS ? </li></ul>
  3. 3. From Food Apps to Packaging Material <ul><li>Food adulteration </li></ul><ul><li>CID in Plant breeding </li></ul><ul><li>Soils / Sediments </li></ul><ul><li>Carbonates </li></ul><ul><li>Green Packaging QC </li></ul>
  4. 4. Picarro CM-CRDS Enables…. High-precision δ 13 C analysis of solids & liquids Combustion Module (CM) Liaison ™ Interface CRDS
  5. 5. Liaison Universal Interface 1. Admits gas sample from front-end 2. Collects current processed sample 3. Delivers previous sample to CRDS 4. Purges gas bag to collect next sample In Parallel: Fully Automated
  6. 6. Excellent precision <ul><li>5 hr analysis of 29 solid samples of acetanilide std: </li></ul><ul><li>=> Excellent precision: SD < 0.1 ‰ </li></ul>0 1 2 3 4 5 Hrs
  7. 7. Honey Samples Analysis Sample Delta ( ‰ ) S.D.
