SIM Hydrogen sensor
SIM Scientific Instruments Manufacturer has developed a hydrogen sensor that is fully integrated into the Agilent gas chromatographs and continuously detecting the gas concentration in the GC oven. An external version is available compatible with any GC of the market.
The sensor incorporates acoustic alarm system and optical alarm with LED. One green LED shows the ready status of the hydrogen sensor with no hydrogen in the GC oven. If the H2 concentration is above a threshold level of 10% of LEL (0.4%), the first red LED will light up and an acoustic signal will be transmitted. At a detected H2 limit of 25% LEL (1.0%), an alarm signal will sound and the carrier gas will automatically be switched to an inert gas.
