Isokinetic Sampling Glassware
The purpose is to capture particles that particle under an outlined area in a definite time without disturbing their paths. The velocity of the air going into the sampling probe nozzle is adequate to the speed of the undisturbed air at that time. The air is disturbed as little as possible in order that the identical particles (no more and no less) come in the nozzle as would have passed the world of the nozzle had it not been there. Numerous products are available for this purpose from suppliers of scientific and testing equipment.
