GPC detector problems
Posted: Wed Mar 13, 2013 11:23 am
Hi,
We have an GPC Waters Breeze System(Isocratic HPLC pump 1515; 717 plus Autosampler, 2414 Refractive Index detector and 3 columns Styragel HR1xHR 0.5xHR0.5; Flow rate = 1 ml/min).In this moment we changed 2 valves on the detector:Solenoid valve and Relief valve, because it flows in the same time on the purje mode and on the analysis.Four mounths after, this the GPC system it works, but after it begining again .What's happening? In this moment we change the flow rate= 0,5 ml/min, and it works normal(p=400 psi) .If I try to grow up the flow rate to 1 ml/ min,it flow again. Please help me.
Thank you,
Ileana
