PER- AND POLYFLUORINATED SUBSTANCES (PFAS)
As PFAS analysis continues to be a focus for laboratories around the world, CIL continues to add new compounds to our suite of native and isotopically labeled standards. New labeled heptanoic and dodecanoic acids round out our offerings of the longer chain acids and offer a distinct advantage with uniformly 13C7- and 13C12- labeling. CIL now offers native PFOS, N-MeFOSAA and N-EtFOSAA standards as mixtures of their straight-chain and branched isomers, as stipulated in US EPA Method 537.1. New Fluorotelomer Sulfonates (FTS) are now becoming available; look for more of these in the very near future.

POLYCHLORINATED BIPHENYLS (PCB)
A 13C-labeled standard of PCB-162 and native standards of PCB-147 and PCB-166 have been formulated in support of a new testing method being developed by the US EPA. A diluted calibration standard for US EPA Method 1668C provides an expanded range option for low-level analysis. CIL has historically offered separate dioxin-like and marker PCB mixtures, and now has 13C-labeled and native mixtures that contain all WHO-12 dioxin-like and 6 marker PCBs to allow researchers to analyze for all 18 target congeners using one reference mixture.

PESTICIDES/HERBICIDES AND PESTICIDE METABOLITES
The cis isomer of DBCA ((2,2-dibromovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid) is the primary diagnostic metabolite of deltamethrin, corresponding to cis/trans-DCCA which are non-specific metabolites of permethrin, cypermethrin, and cyfluthrin. Nitenpyram is the latest neonicotinoid to be added to CIL’s offerings, and the first nitromethylene neonicotinoid insecticide. MCPA is a legacy phenoxyacetic herbicide that has received attention recently as more glyphosate-resistant weeds emerge.
