After passing the sample through the membrane, examine the filter directly with incident light or render it transparent so that you can apply transmitted light. This test is performed to determine the amount of time necessary for the cleanroom and its system to reach a steady state cleanliness level after a brief particle generation event within the clean space. Sample flow rate accuracy is therefore, critical to mitigating flow rate errors caused while sampling actual volume for a fixed sample time. In all monitoring, steps should be taken to ensure that the sample probe does not pick up particle counts from the motor/exhaust of the test instrument or from adjacent operations.
