Picarro has partnered with OICO to develop a turnkey analyser for measuring total organic carbon (TOC) as well as the carbon stable isotope ratio.
The Itoc-CRDS works with solids, liquids, sludges and slurries.
It can 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.
This isotopic CO2 analyser is based on wavelength scanned cavity ring-down spectroscopy (WS-CRDS).
The CO2 is introduced directly into the WS-CRDS unit, without the need for drying or other purification, in contrast to legacy isotope analysers based on isotope ratio mass spectrometry (IRMS).
Applications for this instrument include origin of food (appellation of origin) and adulteration analyses for such products as: wine, fruit juice, edible oils, seeds, nuts, fruits, chocolate and dairy products.
This system can be used for carbon isotope distribution in soils, sediments and plant materials as well as limnology, hydrobiology, marine and freshwater ecosystem studies.
