Question
I’m injecting a lot of cell lysates on my
804 column and I want to know if there is a disposable guard column system that I could be using. It seems that most guard columns are $500 USD so it is a shame to have to go through a guard column every 15-20 AnSEC runs.

Answer
We are sorry but we do not deal with a disposable guard column for Shodex columns.
And in the case of the guard column clogging, it may be possible to regenerate it by running the eluent from the outlet of the column, during the analysis with using a substitute column.
