iTOC-CRDS Isotopic Carbon Analyzer System
The Ultimate Integrated System for Flexible Combined Carbon Analysis
Truly integrated, compact system
Easy-to-use and flexible
High precision measurement of δ13C and TIC/TOC
The iTOC-CRDS Isotopic Carbon Analyzer combines an OI Analytical total organic carbon (TOC) analyzer with a Picarro G1111-i Cavity Ring-Down Spectrometer (CRDS) to measure organic carbon (TOC), inorganic carbon (TIC), or total carbon (TC) along with the isotopic ratio of 12C and 13C carbon (δ13C). This combined technique supports the analysis of aqueous and solid samples.
Organic compounds in aqueous samples can be oxidized in the reaction chamber of the TOC Analyzer using heated sodium persulfate (Na2S2O8). Alternatively, solid samples can be placed in a quartz crucible and oxidized by high temperature combustion in the Solids Module. The CO2 produced by either method is then introduced into the Picarro isotopic CO2 analyzer for measurement of the 13C/12C isotope ratio. The instrument can be configured with an autosampler for use with aqueous samples.
Applications for this instrument include origin of food (appellation of origin) and adulteration analyses for such products as wine, fruit juice, edible oils, including olive oil, seeds, nuts, fruits, chocolate, and dairy products. In addition, this system serves environmental science applications such as carbon isotope distribution in soils, sediments, and plant materials as well as limnology, hydrobiology, marine and freshwater ecosystem studies.
