A method is suggested for the determination of 1,3,5-trinitro-1,3,5-triazacyclohexane in workroom atmosphere. The substance is trapped in a sampling tube containing glass microfibres and activated silica gel, decomposed with sulphuric acid to give formaldehyde, the latter is reacted with 1,8-dihydroxynaphthalene-3,6-disulphonic acid, and the derivative of dibenzoxanthiliumtetrasulphonic acid formed is determined protometrically at 580 nm.
