For our analysis we are using the following MolSieve packed column:
#G3591-80074 MolSieve 5A, 80/100, 3 ft (0.91 M), 1/8 in. OD, 2 mm ID.
We need to replace this column to get twice faster analysis. For example for CH4 which has the time of retention of 4.5min at the moment, we need such column to get it on 2.3min.
In this situation, the only solution is to replace the #G3591-8007 column with one similar by the length, but with different parameters (mesh value, or to use 13X type instead of 5A, which has faster time of analysis).
Please note that changing the method parameters is not accepted, the only solution is packed column replacement with a faster analysis one.
We are thinking to replace with the following column:
#G3591-80028 MolSieve 13X, 45/60, 3 ft (0.91 M), 1/8 in. OD, 2 mm ID.
But we are not sure on it, so please advice.
Thank you in advance.
