New Dimension in Chromatography - Halo® 1.5

Designed for separation of novel and legacy short chain and long chain PFAS compounds containing branched and linear isomers, along with EPA methodology requirements in mind, HALO® PFAS offers a holistic solution.

A PFAS specific delay column is optimized to prevent background PFAS contamination from interfering with the sample results. HALO® PFAS solution delivers excellent selectivity, peak shape and necessary retention to perform fast, high-resolution separations.
