1. A method for assessing the state of organisms and natural products emitting substances into the surrounding atmosphere wherein one or more of said substances are determined in a gaseous mixture, determination being done 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, wherein the gaseous mixture comprises main and secondary components and at least one main component is determined in the concentration range greater than or equal to 0.1 percent by volume and at least one secondary component in the concentration range less than or equal to 0.1 percent by volume. |
