The present disclosure relates to a method for analysis by mass spectrometer of liquid and/or gaseous samples, and to an apparatus for carrying out said method. A mass spectrometer is used which has a first flow element for liquid samples and a second flow element for gaseous samples.

Online mass spectrometer for real-time detection of volatile components from the gas and liquid phase for process analysis

For the continuous quantitative determination of volatile substances in lids, such as in particular halogenated hydrocarbons in process or waste waters, the invention proposes a corresponding method, according to which the liquid is led past a liquid-impermeable, but gas-permeable membrane and that the strippable substances in the liquid in their gas phase pass through the membrane and lead same through a measuring cell. An apparatus for performing the method is characterized by a flow chamber provided with a liquid-impermeable, but gas-permeable membrane for the liquids to be investigated and by a measuring cell for the substances to be investigated located on the membrane side remote from the flow chamber.
