An alternative to an extra tank is just to use a cheap disposable
3-way stopcock between the sheath tank and a 0.22 micron syringe
filter. Switch to the side port to syringe 70% EtOH up to the nozzle
and back along the sample line. Then switch back to sheath flow. We
do this routinely without precipitation problems. So that the sheath
saline is clean enough for the small, 0.22 micron syringe filter to
flow all day without appreciable pressure drop, we have a 0.47 micron
"pre-filter" at the sheath tank.
