Compound-Specific Isotope Analysis (CSIA)
(C, H, Cl, Br)
“Unraveling Contaminant Sources Through Precision Isotope Analysis.”
A Precision Tool for Tracing Organic Contaminants
IT² is internationally recognized for its expertise in Compound-Specific Isotope Analysis (CSIA) — a powerful approach that measures the isotopic composition of individual organic contaminants to unravel their sources and transformation processes. By analyzing stable isotopes of carbon (δ¹³C), hydrogen (δ²H), chlorine (δ³⁷Cl), and bromine (δ⁸¹Br) within specific compounds, CSIA enables clear differentiation between contaminant origins, manufacturing signatures, and in-situ degradation pathways.
Unraveling Sources, Pathways, and Processes
This allows for quantitative assessment of natural attenuation, biodegradation, and remediation effectiveness directly in the field context. IT²’s CSIA program integrates advanced GC-IRMS and GC-MS platforms with proprietary extraction and purification protocols developed for challenging matrices such as groundwater, soil, and NAPL samples.
Turning Isotopic Evidence into Environmental Insight
Through its combination of precision analytics and interpretive expertise, IT² delivers robust isotopic evidence that supports environmental forensics, source apportionment, and performance verification of in-situ treatment technologies.
