There are good chemistry reasons why you won't find HS methods for HCO, so don't bother.

There are special sampling traps which monitor HCO and react it with Phenyl Hydrazine and measure by desorption and HPLC analysis.

This is a method used in the US and in Japan for measuring HCO in the air of buildings.

Call Supelco Technical Service for assistance.

800-359-3041 in the USA.

Would extraction of formaldehyde from a liquid protein work the same way with the solvent desorption tubes?
