What are the reasons for failure to ignite in gas chromatography?
Haha, this problem has troubled us for a long time. There are many reasons: blocked air passages, problems with the electronic igniter, insufficient air pressure, and so on. The solution is simple and straightforward: you just buy a lighter and light it yourself.
1`Hydrogen gas blockage. 2. The nozzle is clogged; the air resistance flow rate was measured to be 30 ml/min for hydrogen and 300 ml/min for air. Check whether the nozzle is clogged, and clean it with isopropyl alcohol or propanol
1. Gas source pressure 2. Blockage present or not 3. Improper hydrogen-to-air ratio 4. Reduced setting after ignition, resulting in shutdown. It is likely that the hydrogen-to-air ratio is not appropriate.
