I would like to ask about the types of closed sampling devices and their applications
Thread Content
There are many types of process media used in such devices. I would like to ask how to choose the appropriate closed-loop sampler, especially for dirty materials – our ordinary closed-loop samplers often get clogged; do we need to flush them with clean medium after each sampling operation? What good ideas does everyone have?
Nitrogen purging and filters are both good approaches, but it is also necessary to start from the existing process flow and the design principles for sealing, and to develop a solution based on the medium and operating conditions.
