Abstract
The invention relates to a method for assessing the state of organisms and natural products wherein one or more substances are determined in a gaseous mixture, determination being effected by a mass spectrometer wherein an ion beam acts on the sample of gaseous mixture in high vacuum in such a way that the test molecules are ionized with the aid of the internal energy of the ions of the ion beam, and the values obtained upon determination are evaluated for assessing the state.Further, the invention relates to a method for analyzing a gaseous mixture with one or more main components and one or more secondary components wherein at least one main component is determined in the concentration range greater than or equal to 0.1 percent by volume and one secondary component in the concentration range of less than or equal to 0.1 percent by volume by a mass spectrometer wherein an ion beam acts on the sample of gaseous mixture in high vacuum in such a way that the test molecules are ionized with the aid of the internal energy of the ions of the ion beam, and to an apparatus for analyzing a gaseous mixture comprising a mass spectrometer with a gas delivery system wherein a molecular beam is…
