The Picarro Micro-Combustion Module (A0214) effectively removes spectral interference for commonly occurring alcohols and plant products, including multicomponent mixtures of alcohols, terpenes, and green leaf volatiles. It has optimal efficacy for samples containing total organics in concentrations typical for many plant extracts (<0.5%), due to the production of nascent water.

  • Treat samples inline to decompose interfering organics
  • Improve data quality for water isotope analysis
  • Easily deploy in a laboratory or in the field


The Micro-Combustion Module eliminates organic interferences using an inline process. It is installed between a Picarro Vaporizer (A0211) and a L2130-or L2140-water isotope analyzer for seamless operation. It passes a gaseous phase sample from the vaporizer over an enclosed element, and the resulting oxidation converts organics into minute quantities of carbon dioxide and nascent water.
