SKC 225-9594 SKC BioSampler - Manual (Page 5)

Caution: When operating correctly, the collection liquid in the BioSampler
should be swirling gently up the inner wall of the sampler, wett ing
it where the nozzles output onto the inner wall. It is important to
visually monitor the following:
a. That there is enough collection liquid in the vessel to wet the in-
ner wall at the location where the nozzles output onto the inner
wall. If this is not occurring, add more collection liquid.
b. That there is not excessive bubbling which indicates that there
is too much collection liquid in the vessel. If excessive bubbling
occurs, decrease the amount of collection liquid in the vessel.
5. When ready to sample, remove foil or Parafi lm from the BioSampler and
connect the outlet to the vacuum pump.
6. Sample for the desired sampling period.
7. Aft er sampling is complete, record the sampling time. Volume of air passed
through the BioSampler can be calculated using the formula
V [Liter] = Q
s
[L/min] x t [min].
8. Disassemble the BioSampler.
