Abstract
A detector for enzymatically determining components in gases and aerosols and includes a porous filter disposed in a housing. The filler absorbs the aqueous reagent solution, the substrates and the enzymes and is brought into communication with a sample to be investigated. The detector of the invention is improved in that a separate preparation of the components needed for the detection takes place in the housing itself. The components combine without additional ancillary equipment or manual movements. The components are combined in that a porous filler is accommodated in a holder and is tightly held thereagainst and a filler tip projects outwardly therefrom. The filler tip is dipped in a supply vessel containing the reagent solution. A penetratable cover membrane which is impermeable to water is arranged between the filler tip and the supply vessel.
