摘要： A portable gas analysis apparatus for conducting a gas flow, in particular for highly volatile compounds, includes a seeker measurement path and a separation measurement path. The seeker measurement path extends from a sample gas inlet opening to a first air exit opening, wherein a connecting path branches off from the seeker measurement path to a separation measurement path, and said separation measurement path extends from the connecting path to a second air exit opening and is connected to a carrier gas inlet opening, wherein the gas analysis apparatus has a control element which is designed for reversing the gas flow in the connecting path.

摘要： A portable gas analysis device having a separating column and a detector. The separating column is composed as a multi-capillary unit from parallel individual capillaries and, depending on the length, is bent into a compact shape, preferably even wound into multiple turns. A thermally conductive casing and a thermal stabilizing device are provided for the multi-capillary unit. The thermal stabilizing device comprises a temperature sensor, a heating element and control electronics. The casing protects the sensitive multi-capillary unit from mechanical actions; it acts as a protective space. The temperature-controlled casing also forms a space in which uniform and controlled conditions prevail and which in particular is isolated from the temperature and humidity of the environment, allowing reliable measurements outside a laboratory environment, in the field. This double effect of the casing for the capillaries in conjunction with the compact dimensions forms the true essence of the invention.

摘要： A method for a multistep analysis of a measuring program of a portable gas measuring device includes performing a factory setting of the portable gas measuring device, connecting a container having a known gas standard and performing a reference measurement, wherein a multidimensional reference measurement is recorded, selecting a measuring program for target materials from a list on the device, performing a measurement on a sample in dependence on the selected measuring program, wherein a multidimensional measured variable is recorded, automatically performing an analysis to identify at least one of the one or more target materials in the sample and the respective concentrations thereof, wherein the analysis is based on the multidimensional measured variable from the measurement on the sample, the multidimensional reference measurement for the gas standard, the values for the plurality of target materials or measuring programs, and the factory setting for the portable gas measuring device.
