Re: Do you monitor both 0.5 and 5 micron in ISO Class 8 cleanrooms?


I use Sedigraph too...but for wildly different things.

Air sampling and Sedigraph particle size measurement are like apples and warm. Nothing at all to do with each other.
Air sampling typically uses a suction port running through a laser PS measurement grid whereas Sedigraph typically has discrete particles in fluid suspension.

Do an image search for "cleanroom air sampling machine" and the difference will jump right out at you (I can't figure out how to put a pic in here).
Thanks to Ninja for your informative Post and/or Attachment!
