The sample bag inflates as a result of the interior pressure drop. This pneumatic technique allows the air sample to enter the bag directly without passing through the pump, protecting the pump from sample contaminants and the sample from pump contaminants. SKC Ltd.

All surfaces in contact with the sample are constructed of inert materials. An air sample bag is connected to the inside sample inlet port and the chamber is closed, providing an airtight seal. An air sample pump is connected to the outside vacuum outlet port. When activated, the pump evacuates air from inside the chamber. The sample bag inflates as a result of the interior pressure drop. The sampling bag is connected to a piece of PTFE tubing, which passes through the face plate via a stainless steel compression fitting.
The sample should never come into contact with anything other than inert PTFE or stainless steel. SKC Ltd. You need JavaScript enabled to view it. What is Air Sampling? Guide to the Website.
