Inquiry (采购产品): sensing system for trace levels (ppt) of vapours Dear sir/madam I’m a post doc at the University of Wales Bangor and my project involves a sensing system for trace levels (ppt) of vapours. We have already designed the required sensing element, however the vapour sampling system is still in the early design stage, therefore I was wondering if you have any small/handheld sampling systems?
