Troubleshooting: Thermo Dionex ICS 2100- leak from secondary pump spacer with drain. Help please!
Hello chromatographers!
I'm working with a Thermo Dionex ICS2100 IC system and I feel like I've been arm wrestling this system for the past 3 months with different problems popping up.
On my last run, the pressure started fluctuating like crazy in a cyclical pattern. This pointed to a pump issue, so I cleaned out both the primary and secondary pumps with milli-Q waterand wiped off all salty residue. Easy enough!
However, after reassembling the primary and secondary pump heads, the bottom drain on the spacer for the secondary pump head started dripping water!
A couple of questions for the chromatography community: (1) is this normal for the drain on the secondary spacer to be dripping liquid? I've not seen this happen on this instrument before, but I know I can attach drain tubing to it so maybe this isn't a big deal? (2) What is causing the drip from the secondary pump drain?
Thank you for your time! Y'all rock!
