一般描述

Ascentis® Express PFAS is a high-speed, high-performance liquid chromatography column based on the proven Fused-Core® particle design. The Fused-Core® particle provides a thin porous shell of high-purity silica surrounding a solid silica core. This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0.5 μm thick porous shell and the small overall particle size of 2.7 μm. The densely bonded, extensively endcapped ODS stationary phase of Ascentis® Express PFAS provides an application tested solution for PFAS analysis.

分析说明

Target analytes include short chain and long chain per- and polyfluoroalkyl substances (PFAS), including branched and linear isomers.

LC-MS Analysis of PFAS Compounds

LC-MS method separates 32 PFAS compounds in drinking water following EPA methods 533, 537, and 537.1. EPA 8327.

Fast and High-Resolution LC-MS Separation of PFAS

Liquid Chromatography–Mass Spectrometry (LC-MS) separation of 33 PFAS (Per- and poly-fluoroalkyl substances) using a superficially porous silica particles (SPP) based Ascentis® Express C18 column.

Quantitative Analysis of PFAS in Drinking Water by LCMS

Simultaneous determination of 27 PFAS chemical compounds after enriching the water samples with SPE using a Supelclean® ENVI-WAX weak anion exchange tube.

Obtaining Ultrapure Water for Sensitive PFAS Analysis by LC-MS

Sensitive PFAS testing can be performed with ultrapure water from a Milli-Q® IQ 7 system, which eliminates detectable PFAS for reliable LC-MS/MS results. See the science, see the proof.
