Hydrogen is an ideal alternative to helium as a carrier gas; it is expanding the use of hydrogen in GC and GC/MS, offering a faster analysis. But unfortunately the use of hydrogen could also be dangerous, because of the risk of explosion. In Ingenieria Analitica, we are suppliers of a wide range of Hydrogen Sensors for any GC or GC/MS model. By constantly monitoring the hydrogen concentration in the GC oven, in case the limit is exceeded the alarm system is activated and automatically interrupts the supply, switching to an inert gas such as helium to remove the danger and prevent flow columns run out.
