FAQ's
- I need to certify my cleanroom. Which particle counters are best for this?
- Per ISO, statistical analysis is required if the number of locations to be measured is(as the area calculated) > 2 and < 9. If, based on my area, the number of locations to be sampled is 7, can I perform counting at extra locations (up to 10) and avoid the statistical analysis?
- Which particles counters should I use for spot checking versus continuous monitoring?
- At what temperature, relative humidity and absolute humidity are cleanrooms certified?
- What should the course of action be when the particle count exceeds 100 (0.5 micron) in class 100 ?
- What is the frequency for performing a zero count on the LASAIR III? How do you perform the zero count? What is the acceptance criterion for the zero count?
