Agilent 1100 Retention times shifting
I am running a reverse phase system on an Agilent 1100 with a quantenary pump. My retention tiimes are shifting and the pressure is higher while running.
Also when the purge valve is open the pressure is higher than it used to be.
I think I need to do the PM on it but wanted to see if there was anything else I should look at.
