Drug One is a non-polar column that will elute drugs in
the same order as an OV-1 or OV-101 packed column.
Drug Two is a moderately polar column that will give a
retention order similar to OV-17. Drug Three is a special
phase formulated for the analysis of anticonvulsants.

tech tip
Temperature limits
Our GC capillary columns are temperature rated. In some cases,
we list two maximum operating temperatures, the lower one is
for isothermal condition and the higher one for temperatureprogrammed
condition.
