Abstract: A process for determination of one component of very low concentration in a test gas, which is guided in a supply line for concentration of the component across a sample collector, whose amassed quantity of samples is relinquished to a detection sensor. The arrangement makes available a measurement signal even during the collection of the sample. It also makes even the individual components of a multicomponent test gas detectable and a component-specific cross sensitivity of the detection sensor controllable. For this, the following process steps are provided: the test gas is first guided across the detection sensor 3 and then across the multistaged sample collector 7 having arrangements for separation of the several components; then after interruption of the supply of test gas, each individual stage 4, 5 and 6 separately relinquishes its separated component to the detection sensor 3.

Abstract: With a fluid fuel driven standard heating for motor vehicles, whose combustion chambers are equipped as vaporizer burners, a heater plug with open heater coils up to now would be installed in the usual way. What is disadvantageous for the operation, particularly in the starting, is the voltage dependence of such a heater plug. Also, with time an increasing carbonization would be established. According to the invention the vaporizing of the liquid fuel occurs under a seal by the use of a rod heater plug. The ignition can--independent of voltage--occur with the help of a spark plug (high voltage electrode). In a construction design the vaporizer is developed as a heat pipe, in which the rod heater plug is arranged.
