SAFETY GAS DETECTION
Get all the benefits of the H2 generator as carrier gas ... instead of He
The hydrogen sensor is one more safety device available that allows you to secure the use of hydrogen in your GCs. It continuously checks potential leak of hydrogen in the GC oven. This sensor has been designed to automatically stop the generator when the amount of hydrogen is higher than the safety threshold.
What is a Hydrogen sensor and how it works?
The H2 Sensor is installed in the GC oven for continuous monitoring of H2 concentrations in the oven air. 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.
Advantages to use a Hydrogen sensor when using Hydrogen as Carrier Gas
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.
