Excellent selectivity for fluorinated compounds

HALO PFAS and HALO PFAS Delay columns have been developed specifically for the analysis of Per- and polyfluoroalkyl substances (PFAS). The densely bonded, extensively endcapped ODS stationary phase of HALO PFAS provides an application assured and method qualified solution for PFAS analysis. Every HALO^® PFAS lot is quality assurance tested by LC-MS/MS analysis of a mix of 17 PFAS consisting of a broad range of short and long chain compounds.

Advantages of the HALO PFAS columns:

Excellent selectivity and resolution for EPA methods 537.1, 533 and 8327
Application-assured through method qualified lot analysis
Optimal 2.7 μm Fused-Core^® particle for rugged, reliable performance delivering high efficiency, low back pressure separations
Endcapped alkyl phases for high sensitivity (no bleed) LCMS analysis
Pressure limit: 600 bar/9000 psi

HALO PFAS Delay is an application assured column solution. The delay column is used to prevent background PFAS contamination from interfering with the PFAS of interest that are separated with the analytical column. The delay column bonded phase is a highly retentive endcapped silane chosen for its ability to demonstrate delay of background instrument PFAS contamination across multiple mobile phase conditions. For this reason, the HALO PFAS Delay column is placed upstream of the sample injector.
