CP-Chirasil-Dex CB Columns
DB-1ms GC Columns
J&W DB-1ms is a nonpolar, low-bleed GC column, with an extended upper temperature limit and excellent inertness for acids and bases. The low-bleed stationary phase reduces column contribution to background noise, resulting in a higher signal-to-noise ratio and better sensitivity for improved mass-spectral purity and accurate library identification.
Bonded and crosslinked, this highly inert column provides maximum response for active analytes commonly found in drug screening and environmental analyses.
