Environmental Contaminant Standards - New Products

Following please find a listing of new items that became available from CIL since the first and second quarters 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)
Tetrafluoro-2-(heptafluoropropoxy) propanoic acid, or more commonly “HFPO-DA” or “GenX” is the dimerized product of a fluorinated ether compound developed as a replacement for PFOA. Extensive use of the fluoropolymer, and subsequent identification in numerous water sources has led to extensive research on this compound. As CIL continues to complete labeled and unlabeled PFAS individual standards we are now able to prepare more extensive PFAS mixtures for both regulatory methods and custom projects. CIL is pleased to introduce U.S. EPA Method 537 (original version) standard mixtures. Look for the revised Method 537.1 mixtures in the near future.

NITROSAMINES
N-Nitroso-N-methyl-4-aminobutyric acid (NMBA) has recently been detected in the blood pressure medicines Losartan and Irbesartan, which were initially recalled along with Valsartan due to the presence of related compounds N-Nitrosodimethylamine (NDMA) and N-Nitrosodiethylamine (NDEA). CIL has historically offered standards for NDMA and NDEA, and recently synthesized NMBA standards in response to the need for analyzing this third probable carcinogen detected in popular blood pressure medicines.

FLAME RETARDANTS
Two new 13C-PBDE mixtures provide an alternative approach to measuring the most commonly found BDE congeners. A new PAR mixture includes a comprehensive list of native PBDE and other brominated flame-retardant compounds of high concern. This mixture can be used with our calibration standard EO-5319-A and supporting spiking solutions.
