I want to determine trace quantities of NO (nitrogen oxide) in a mainly hydrogen gas, and I guess that a PFPD detector might do the job (alternatively, a NPD detector can also do the analyses, but I do not like a NPD, because the bead in this detector needs constant attention). Does anyone know of an alternative quick and easy way to determine trace quantities of NO? ... I am aware of literature describing the derivatisation of NO with DNPH, followed by HPLC, but I would prefer a more direct analyses.

Chrompak(Varian) describe an application using CP-Pora-PLOT Q 25m x 0.25mm df 8um. You could contact them for more details.
