Question
We have purchased two of your GPC columns and a guard column to run our system in DMF. When we first received the columns and started using our system the pressure was at ~32 bar. Over the course of several months our pressure shot up to ~107 bar. I was wondering if you had any suggestions on how we can take care of this issue? Do you think replacing our guard column could solve the problem, if so, how can we test this before purchasing a new guard column?

 
 

Answer
Could you check the pressure of the guard column?
You can check the pressure with connecting only the guard column to the system.
I would also like to recommend you to check the pressure of the system without the guard column.
If the pressure of the guard column is high, we recommend to replace the guard column.
