Agilent DB-ALC GC Columns

Agilent J&W DB-ALC1 and DB-ALC2 analytical columns enable two minute blood alcohol content analysis, reducing run time by one third compared to other blood alcohol analysis columns. Due to its unique polarity, DB-ALC2 also provides better resolution of key ethanol/acetone peaks than other available blood alcohol confirmation columns. These columns are suitable for both headspace analysis and direct injections.

A 7 inch cage is the most common GC column format, compatible with Agilent 5890, 6890, 7820, 7890, 8860, and 8890 series GC systems, and all non-Agilent GC systems with a similarly sized oven. The 5 inch cage format is designed for smaller GC ovens e.g. for the Agilent GC 6850.


DB-ALC Intuvo GC Columns with Smart Key are also available, which are specifically designed for use with the Intuvo 9000 GC instrument.
