develop HCHO gas detection equipment

Formaldehyde (/ f ə r ˈ m æ l d ə h aɪ d / fer-mal-duh-hahyd, also / f ɔːr ˈ m æ l d ə h aɪ d / fawr-) (systematic name methanal) is a naturally occurring organic compound with the formula CH 2 O (H−CHO). The pure compound is a pungent-smelling colourless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous ...

    The tracer gas escapes at a leak opening and then, being lighter than air, permeates to the surface through the soil and pavement. The leak is located by scanning the ground surface directly above the pipe with a highly sensitive gas detector. Although helium is used in the US, the most commonly used tracer gas worldwide is hydrogen (H2).
