Item #:
1229X63
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...
