Picarro, Inc. has partnered with the O.I. Corporation to develop a turnkey analyser for the measurement of total organic carbon (TOC), as well as the carbon stable isotope ratio (δ13C).
The new iTOC-CRDS works directly with solids, liquids, sludges and slurries, and is formally launched at the Pittcon® 2009 technical conference and exhibition in Chicago this week. The iTOC-CRDS is an integrated, small and easy-to-use system that can either perform wet oxidation on the carbon content of aqueous solutions, or combustion of solid/semi-solid organic materials to generate CO2.
The Picarro isotopic analyser then measures the liberated CO2 and is proven to be effective, based on wavelength scanned cavity ringdown spectroscopy (WS-CRDS). The system delivers δ13C precision as high as 0.2‰ (permil) in seconds or minutes, depending on sample specifics.
In both cases, the CO2 is introduced directly into the WS-CRDS unit with no drying or other purification necessary.
