Quality Control Technique for High-Volume Atmospheric Particulate Sampler

Quality control technique was developed for high-volume atmospheric particulate sampler. The flow meter of PMS-800 sampler was calibrated by an ISA1932 nozzle flow meter, and the global collection efficiency of PMS-800 sampler was tested by a type 2031 mobile sampler. The results show that the flowrate relative deviation between ISA1932 nozzle flow meter and PMS-800 sampler flow meter is less than 5%, and the global collection efficiency relative deviation between type 2031 sampler and PMS-800 sampler is less than 10%. The performance of PMS-800 sampler meets the specifications with the request of the Comprehensive Nuclear-Test-Ban Treaty. This method can be applied to quality control for high-volume atmospheric particulate sampler.
