Environmental Contaminant Standards - New Products
ShareFollowing please find a listing of new items that became available from CIL since the third quarter of 2019. 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, an “information file” with the congeners and concentrations is part of the product listing. 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 POLYFLUORINATED SUBSTANCES (PFAS)
CIL recently completed production of several fluorotelomer sulfonates (FTS), and now offers them as standard solutions in their salt forms. These compounds are found in AFFF firefighting foam and are commonly included in analytical methods at water testing laboratories. Note that the CIL isotopically labeled FTSs provide an M+6 mass shift from native to provide enhanced separation compared to other commercially available M+2 products. The N-Methylperfluorooctanesulfonamide is a transformation product sometimes found in environmental samples where PFAS contamination has occurred. While not always included in analytical protocols, these compounds supplement the PFAS product line, and are requested from time to time. 9Cl-PF3ONS is a component of the polyfluorinated ether sulfonate commonly known as “F-53B” which was developed as a replacement for PFOS. Recent studies have shown large amounts of this and related compounds (“HFPO-DA”, “DONA”, and “11Cl-PF3OUdS”) in surface and ground waters, and these compounds have already been included in the U.S. EPA’s revised Method 537.1. CIL has recently transitioned our native and isotopically labeled perfluoropentanoic acid standards to their sodium salt forms and re-formulated. Please note the new part#s for these products.

POPs MIXTURES
With growing target lists, it becomes quite costly and involved to purchase all individual standards to formulate mixtures, bearing in mind the risk of error and even simple preparation variability contributing to uncertainty and variance in data. In anticipation of adoption of JECS methods for POPs, Phenols/Parabens and Neonicotinoid/Neonicotinoid Metabolite analyses in other parts of the world, CIL offers mixtures compatible with the analyte groups targeted in the study. The mixtures listed below were produced to support phases of the Japan Environment and Children’s Study (JECS) launched by Japan’s National Institute for Environmental Studies (NIES).

PHARMACEUTICAL AND PERSONAL CARE PRODUCTS (PPCP)
Bisphenol A (BPA) is a synthetic compound that has long been used in the production of a range of consumer products, including dyes used in thermal receipt paper, polycarbonate plastics, and epoxy resins.CIL has produced a deuterated BPA standard which can be used as a syringe or field spiking standard in conjunction with the 13C-labeled internal standard (CLM-4325-1.2).
