The advantages of hydrogen are clear (fast analysis, high efficiency, reduced costs and prolonged column life time), but it does have one really big disadvantage:
hydrogen is an explosive gas. An undetected gas leak can occur with a broken column or a leaking connection. The danger is that an undetected gas leak could result in an explosion in the GC oven placing laboratories and their personnel at risk.
Our H2 Clever Sensor ensures the safe use of hydrogen in GC analysis. The measured gas concentration is shown on the LCD screen of the external controller. When the hydrogen concentration reaches the user defined level, typically between 25% and 50% LEL (equal to 1%-2% by Vol H2), the LCD screen starts flashing, an acoustic signal is transmitted and the carrier gas will automatically be switched to an inert gas.
This important feature eliminates the risks and at the same time ensures safety.
The external box is able to support up to 4x sensors and operates as individual channels: it will stop the H2 gas only for the GC in which there is a leak detected.
