A metal-supported porous carbon film wherein metal fine particles with a mean particle diameter of 0. The invention is based on the ion focussing principles of high field asymmetric wave-form ion mobility spectrometry in which an analyzer region is defined by a space between first and second spaced apart electrodes, the analyzer region having a gas inlet and a gas outlet for providing a flow of gas through the analyzer region. In another aspect the invention relates to a flow cytometer system for automatically calculating drop delay. Specifically, the decoding system can reduce the total video decoding time, thereby allowing a surplus memory use time for additional functions of a digital broadcasting receiver. The actuating linkage comprises a first linkage portion interposed between the stationary support member and the first telescoping arm and a second linkage portion interposed between the first and second telescoping arms. The device is able to assemble language objects in the memory to generate compound language solutions.
