Ultrashort-Chain PFAS
The unique properties of ultrashort-chain perfluroalkyl and polyfluoroalkyl substances (PFAS) can result in poor chromatography when attempting to incorparate these analytes into existing PFAS methods. Their high polarity results in limited retention on reversed phase columns making their inclusion in comprehensive PFAS target lists for environmental sample analysis less common.
In order to aid researchers in the detection and quantification of these compounds, Wellington has expanded their PFAS product line to include certified reference standards of ultrashort-chain perfluoroalkylcarboxylic acids and perfluoroalkanesulfonates. Each new product was characterised using an analytical method designed specifically for ultrashort-chain PFAS.

PFAS Mixtures of Linear and Branched Isomers
As the concern surrounding perfluroalkyl and polyfluoroalkyl substances (PFAS) continues to increase due to the recognised impact of these compounds on environmental and human health, the need for ongoing analysis to ensure public safety is paramount.
To support this ananlytical initiative, the chemists at Wellington have prepared quantative isomeric mixtures of both PFOA (br-PFOA) and PFNA (br-PFNA) to allow commercial laboratories to comply with the requirements of U.S. EPA methods 1633, 533, and 537.1. All isometric mixtures listed below contain the linear isomer as well as moni-trifluoromethyl and di-trifluoromethyl branched isomers in ratios that match technical materials as closely as possible, but with an overall chemical purity greater than 98%.
