The DB-1ms is a non-polar, low bleed column with excellent inertness for acids/bases and an extended upper temperature limit. Using low bleed stationary phases reduces the column contribution to background noise resulting in a higher signal to noise ration and better sensitivity. The reduced column bleed results in improved mass spectral purity and accurate library identification. The inertness of the DB-1ms provides maximum response for active analytes commonly found in drug screening and environmental analyses.
