SSP = 46.69
The SSP is the design operating flow rate of the PM10 High Volume Sampler, 1.13 m3/min or 40
CFM, corrected to the current ambient temperature and barometric pressure. Adjust the mass flow
controller to agree with the above determined SSP. This is done by loading the sampler with a piece of
Micro-Quartz filter. Turn on the sampler and allow it to warm up to normal operating conditions. Adjust
the mass flow controller set screw (turning pot) until the flow/pressure recorder reads 46.69. The
sampler should now be sampling at the designed flow rate of 1.13 m3/min or 40 CFM, corrected to
current meteorological conditions.
