Environmental Contaminant Standards - New Products

Following please find a listing of new items that became available from CIL since the fourth quarter of 2021. Updates are being released on a quarterly basis as CIL adds new products for environmental analysis to our inventory. Each part number is a link to the full product listing on the CIL website. In the case of mixtures, a “components and concentrations” file is part of the product listing, as located under the “SDS and Product Documents” portion of the item page. Most items included in these updates are in stock at CIL and available for standard delivery, but please contact CIL for complete product availability.

PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS)

As PFAS research continues to expand, CIL continues to develop new PFAS analytical standards as well. CIL has recently completed the 6:2 FTA, as well as three new fluorotelomer alcohols with the popular 13C2 and D4 (m+6) isotopic labeling. CIL now offers PFOSA as the linear-only isomer, complementing our original PFOSA standard (ULM-10977-1.2) with mixed linear and branched isomers. A 13C-labeled mixture including PFOS/PFOA/PFHxS is now available to match the previously released native mixture. Our C4-C10 PFAS mixture and PFAS-EF-28 mixture have been updated to include newly prepared salt forms of several components. Read more about CIL’s line of PFAS standards here.

PRIORITY POLLUTANTS

Polystyrene-D8 represents our first stable isotope-labeled standard to assist researchers in the rapidly growing field of Microplastics research using pyrolysis GC-MS analysis.

Part number Description Concentration
DLM-221-1.2 Poly(styrene) (styrene-D8, 98%) 1 mg/mL in toluene

 

CANNABINOIDS

(-)-Δ9-Tetrahydrocannabinol (THC) is a major cannabinoid compound produced by the cannabis plant. THC is regulated by a variety of state and federal laws due to its psychoactive effects. Stable isotope-labeled and native THC standards are the latest addition to CIL’s line of cannabinoid standards, joining cannabidiol (CBD) and others. Read more about the full product line, including cannabis pesticide standards, here.

Part number Description Concentration
DLM-10846-1.2 (-)-Δ9-Tetrahydrocannabinol (THC) (methyl-D3, 98%) 100 µg/mL in methanol
ULM-10874-1.2 (-)-Δ9-Tetrahydrocannabinol (THC) (unlabeled) 1000 µg/mL in methanol

 

 
PESTICIDE AND PESTICIDE METABOLITE STANDARDS

While neonicotinoids continue to attract a lot of attention, pyrethroids are widely used in both agricultural and residential settings, and their metabolites are of concern.  CIL is the only commercial source of chrysanthemum dicarboxylic acid, both in native and stable isotope-labeled forms, and several other pyrethroid metabolites are now available in MTBE for compatibility with related compounds that are prone to decomposition in other polar solvents.  Diuron is on the UCMR 1 program Screening Survey (List 2 contaminant). Read more about CIL’s line of pyrethroid standards here.

Part number Description Concentration
CDLM-11258-1.2 Chrysanthemum dicarboxylic acid (propenyl-3-13C, 99%; 3,3,3-D3, 98%) 100 µg/mL in acetonitrile
