We offer a variety of valves for splitting the available inlet ports of your system in two or three (e.g. two-way, three-way valves made of PTFE or PEEK). You can also increase available inlet ports by multiplexing valves providing 12, 16, 18 ports or more. Such valves are a very cost-effective and proven way to multiply the locations you can sample many times. We have tested these valves and offer them integrated into the inlet system of your PTR-MS! All you need to do is go on sampling!
