Abstract: Disclosed are a method and a device for determining characteristics of particles dispersed in gases and liquids in the nano- and microscale size ranges and the number distribution and concentration thereof by use of particle photometry. This can be achieved by producing scattered light measurements in a photometer for a different number of aperture or receiving angles and evaluating particle characteristics from the determined scattered light intensities using evaluation algorithms. The determination of particle characteristics over a size range of several decades is made possible without the need to change or adapt the geometry of the sample measurement chamber.

Abstract: An exhaust gas sampling system includes a main conveying line, a main throughput pump which conveys a sample gas in the main conveying line, a first Venturi nozzle, a second Venturi nozzle, a first control valve, and a second control valve. The first Venturi nozzle and the second Venturi nozzle are connected in parallel and are arranged in the main conveying line upstream of the main throughput pump. The first Venturi nozzle is assigned the first control valve. The second Venturi nozzle is assigned the second control valve. Each of the first control valve and the second control valve are provided as a pinch valve. Each pinch valve has a flexible, hose-like control element and a pressure chamber which is filled with a fluid and which is arranged to surround the flexible, hose-like control element.

Abstract: The present invention relates to a conductive target material comprising essentially one lithium compound, preferably lithium phosphate, and carbon, and also typical impurities. The invention further relates to a process for producing a conductive target material and to the use thereof.
