Agilent DB-1ms Low Bleed GC/MS Columns

J&W DB-1ms is a non-polar, 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 cross-linked, this highly inert column provides maximum response for active analytes commonly found in drug screening and environmental analyses.
