Hello Agilent,
Could hydrogen used as carrier gas in capillary gas chromatography harm or degrade some types of polar stationary phases?

Hi Lars,
Hydrogen is the best possible carrier gas for almost all GC separations (my opinion, but it's cheap, fast and can come from a gas generator) and is not damaging any stationary phase.
You will loose a little in the plate counts, but because the separation is twice as fast as with helium, band broadening due to diffusion goes down and the peaks are sharper (perfect for chiral separations).
