3.5Sample gathers the oil smoke sample with smoke dust sampling instrument, and this just needs to buy many sampling thiefs, causes buying expenses large, stores the room of preserving many, waste resource and fund and manpower, and the quality of instrument can not meet the demands.
3, existing filtrator and cutter for particles are serially connected, and bothersome effort is taken off in each loading and unloading, also easily damage cutter, and sealing effectiveness is bad.
4, when gathering the SVOC sample, require material stainless steel, tetrafluoroethene in the filtrator, the material of the not adsorbed gases such as anodic oxidation aluminium is made.Existing filter membrane holder is made of stainless steel cloth.Be clamped on the bracing frame of aluminum around the filter screen, structurally cause the end face of the fixedly periphery of filter membrane and filter membrane holder not in one plane, easily cause the filter membrane sample to take off difficulty or breakage.
5, present PM
10Nozzle body and the shock plate of cutter are unreasonable in structural design, cause the nozzle of cutter inner nozzle body and the gas flowfield between the shock plate uneven, cause cutting efficiency not good.
