The use of restrictive limits, even when not required by the standard, guarantee higher accuracy in the instrument performance and avoids false counts that appear as particle counts. Each particle channel is represented by a counting bin and totalled with other pulses that are of the same amplitude. Get the latest articles from Pharmaceutical Online delivered to your inbox. Higher sensitivities are required for semiconductor manufacturing plants where cleanroom and. If this is the case, record the decision to use the counter in the test report.

It was intended to provide generic guidance, explain core principles and what constitutes good practice in project management. Please help improve this article by adding citations to reliable sources. Deutsches Institut fur Normung E.
