Abstract
The invention relates to a method for determining the lubrication oil content in an exhaust gas mixture comprising the steps of ionizing the exhaust gas mixture by means of an ion source (), feeding the ions of the exhaust gas mixture to a filter unit () which is embodied as a multipole with a connected voltage source, setting a transmission range of the filter unit () according to a lubrication oil fraction to be measured, filtering out ions with a specific mass outside the transmission range and feeding the other ions to a measuring device () as well as measuring the intensity of the transmitted ions. According to the invention there is provision for the determination of the proportion of the lubrication oil fraction to be measured to be carried out as a global measurement of the intensity of the ions in a step over the transmission range. The invention also relates to a device for carrying out the method. The invention provides an improvement both in the measuring quality and in the measuring speed.
