LDGSS
HIGH PURITY GAS SYSTEM SELECTOR
The LDGSS now brings to the gas industry the most reliable and easy way to provide clean gas to any process GC and online process analyzers. It's compact design, based on high purity connections with an unique diaphragm valve with no dead volume. It becomes the ideal solution for any stream selection needs. This concept allows a quick response time, the possibility to work in vacuum mode and avoid drifting problems.
