The design and construction of a membrane-covered gas miniprobe inlet using a quadrupole mass spectrometer is described. The probe is a metre-long steel capillary tube (o.d. 1.6 mm) terminating in a 4 cm 300 μm o.d. hypodermic needle. Response times

Membrane inlet mass spectrometry has been used to measure the concentrations of dissolved CH4, H2, CO2, and O2 in samples of digestor sludge taken from laboratory scale anaerobic digestors. Addition of low levels of O2 or H2 to samples of sludge in a
