Hello,
we experienced regular drops (every 15- 20 minutes) on baseline on our HPLC 1260 Infinity type. We tried to echange lamp and cell if that could be the problem but it is still happenning. Also we had kinde broken housing plunger but even after exchanging that nothing helped and the drops are still there. Can somebody help me suggest anything we could try to do the get rid of the drop as they are preventing as to run analysis. Thank you so much.
