ABSTRACT:
A gas measurement probe for measuring gas tensions in liquid. The probe comprises a tubing having one end adapted for connection to a gas measurement device, such as a mass spectrometer, a gas chromatograph, an infrared spectrometer or a Raman spectrometer, among others. The second end of the probe is provided with a tip having at least one pore formed in it. The pore is filled with a membrane material which eliminates water from entering, but admits low molecular weight gases. These low molecular weight gases may then be identified by the measurement device.
