We have a GC7890A and an MS 5975C in our lab and the column installed in the system is ASTMD6584.
after the installation of this column we encounter pressure problems, for example we put 3 ml/min but the system only gives 2.8 ml/min. and the system still gives a low pressure signal. we changed the flow to 2 ml/min the system gave 1.8 ml/min
the system always gives a low flow compared to that programmed.
