产品说明
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.
