Other than measuring via Gas Chromatography, what is the easiest way to detect hydrogen in minor quantity, say in micro mol?
If someone suggests on this, many will get benefited, at least to know whether the gas generated during photocatalytic or photoelectrochemical water splitting is really Hydrogen or some unwanted gases.

You could use hydrogen sensors like the catalytic type. There is tapes that change color in the presence of hydrogen even in very small amounts.

Thanks, all of you. Any other suggestions are welcome.
I want to find the easiest way to avoid the doubt of many researchers, who often don't know whether the evolved gases are H2 or something else during photocatalytic water splitting. Gas chromatography can be used later to quantify the gas evolved.
GC is the best not only to quantify but also to prove that H2 is formed
I strongly go with GS/GC though for time being or roughly if you want you can go with tapes, sensors,..
Electrochemical Hydrogen sensors can detect low levels of hydrogen. Minor modifications can also be done to these sensors.
