Environmental Contaminant Standards - New Products
ShareFollowing please find a listing of new items that became available from CIL in the first quarter of 2023. 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)
PER- AND POLYFLUOROALKYL SUBSTANCES (PFAS)
CIL continues to add new PFAS offerings, including recently reformulated PFPrA standards with 4 molar equivalent NaOH for enhanced stability. A new multi-component stable isotope-labeled fluorotelomer sulfonates (FTS) mixture, which includes the 4:2, 6:2, 8:2, and 10:2 FTS compounds, joins the previously released native version. CIL’s labeled FTS standards are 13C2;D4 doubly labeled, offering enhanced M+6 separation for analysis. CIL has also recently released a Method 8327 Surrogate Spiking mixture to accompany the native mixture. For more information on CIL’s full line of PFAS standards, please click here.

The demand for phosphate ester compounds for flame-retardant applications has increased in recent years, leading to more widespread presence in the environment as well as increased human exposure. CIL has offered trialkyl and triaryl phosphate ester standards for several years and is pleased to have recently added many dialkyl and diaryl phosphate ester metabolites to its product offerings for more comprehensive environmental and human exposure analysis studies.

In the environment, dichloroacetic acid (DCA) is found as a by-product of water chlorination as well as a metabolite of industrial solvents. In humans, DCA has found application as a therapeutic treatment for several conditions including: inherited mitochondrial disorders that result in lactic acidosis, pulmonary hypertension, and in certain cases, cancer.1
