1 Scope

The order applies to the total suspended particulate sampler initial verification, use and subsequent verification check.

2 Overview

Total suspended particulates sampler means capable of collecting aerodynamic equivalent diameter < 100μm particle sampler. The basic principle is. a volume of air quality of the membrane by a known constant speed, the suspended particulate matter in the air It is retained on the filter, the filter according to the quality and increase the volume of air through the filter to determine total suspended particles in the air The concentration thereof, and for the determination of the components of particulate matter in the metal, inorganic and organic pollutants. Total suspended particulates sampler consists of sampling head and filter sample clip, power plant exhaust, flow sensors, temperature Part of the sensor, and time controllers.

3 metering performance requirements

3.1 flow indication error Flow indication error should not exceed ± 5%. 3.2 rate Repeatability Flow repeatability should not exceed 2%. 3.3 flow stability Sample flow changes within 6h should not exceed 5%. 3.4 timing error 20min time sampling timing error should not exceed ± 1s. 3.5 Temperature indication error Temperature indication error should not exceed ± 1.0 ℃. 3.6 atmospheric pressure indication error Atmospheric pressure indication error should not exceed ± 500Pa. 3.7 air inlet size deviation Air inlet size deviation should not exceed ± 2.0%. 3.8 load capacity Additional sampling port 4kPa ~ 6kPa load sample flow shall not vary by more than 5%.

4 General technical requirements

4.1 Appearance 4.1.1 The appearance of the instrument should be no injury on the sampler work properly. Host shell around the symmetrical distribution of the membrane Care network formation. 4.1.2 Instrument complete structure, reliable connection, each shall be able to adjust the knob. ......
