Summary:

Particulate in the automotive emission gas is, whether the source of the engine is gasoline or diesel, a continuous target for the analysis because of its harmful feature to the environment, however, the actual measurement has been requiring various complicated procedures with lengthy time. The experiment is given by a measuring device which enables the direct measurement of a single particulate individually based on Helium Microwave Induced Plasma (MIP).This new device consists of three main parts: 1) the introducing section to induce a particulate on the filter as diffusing separately by He sonic velocity, 2) the exciting section with He plasma torch of high energy, and 3) the detecting section with 4 monochromators. Also, the automatic calibration function assures the accurate measurement, saving the manual calibration beforehand. The analyzer allows to measure the particles one by one. This consequence allows the high precision results with a fast, easy operation.The direct, separate measurement of particulate is the core of this procedure where 1) atom, 2) size, and 3) element composition of particulate can be obtained at one measuring time. The experiment showed a measurement result which points a new standard in the particulate analysis of automotive emission field
