SKC Ltd Step by Step Guide to Air Sampling
What is Air Sampling? What is air sampling? Put simply, air sampling is capturing the contaminant from a known volume of air, measuring the amount of contaminant captured, and expressing it as a concentration. This means that an air sample requires three basic measurements: 1. The flow rate of air through the collection medium 2. The sample run
