Accurate, sensitive and rapid detection of carrier gas leaks in a thermal desorption - gas chromatography system is essential for troubleshooting.
Traditional “wet” methods of leak detection using soap solution should be avoided, as this can lead to contamination of the gas lines and TD flow path. Markes offers a portable, highly sensitive leak detector designed to detect helium (or hydrogen) leaks in TD-GC systems.
It works on thermal conductivity principles and is sufficiently sensitive to detect leaks < 0.01 mL/min. Gas leaks are indicated via an LED display and a buzzer. The detector uses re-chargeable batteries and is supplied with the relevant mains powered battery charger.
