Abstract
A sampling device samples gas from a gas stream flowing through a tube to means utilizing the gas to detect the presence or otherwise of particulate contaminants. The device ensures that the sampled flow has at least as many particulate contaminants/unit volume as the main flow. The device divides the flow into two parallel flows and then decelerates one flow before providing the sampled flow. The other flow passes to the utilizing means. The device is particularly useful in the sterile packaging of product to detect microorganisms and other culturable contamination.
