I’ve got a question for those of you running carbonates on a MultiFlow or MultiPrep system, or a Finnigan system using the acid pump. After about 8 months of running waters, I’m gearing up to run some carbonate samples. I was about to test the acid pump (FMI Micropipetter) and found that the pump was frozen. When I took it apart, I found a lot of crystallized phosphoric acid in it (I clearly didn’t run enough water to flush out the acid). Is there an easy way to dissolve the crystals, or does anyone have any suggestions to unfreeze the pump?
