Hey flower,

We have low sample pressure problem (running fine for 30 min and then drop
to 0-20 event/sec)and we observe fluids filled in to the sample tube. This
is still happening even after PM and having DCM tubing changed and as much
as other valves and filters changed.

We do not have contract service so it is expensive to replace the whole
pneumatic and fluidics system. Can I ask you guys if you have similar
problem but get fixed with replacement with any particular part? Our LSRII
is 6 year old.
