• Sufficient flow to the SMPS to minimize diffusional losses. TSI SMPS PARTICLE SIZING INSTRUMENTS SAMPLING INLET SYSTEM ¼”OD TSI Flexible, Conducting Black Tubing PMS LASAIR ISO-KINETIC SAMPLING INLET ¼”OD 1¼”OD ½”OD ¼”OD CLIMET SPECTRO Figure 1. Sampling inlet system for particle sizing instruments. Roof PM-10 Head Vent Valve Transport PSL Test System Vaccum The PM10 inlet was needed to provide representative sampling of coarse particles from the atmosphere, regardless of ambient wind speeds. Without this inlet, the efficiency with which particles entered the sample line would depend on wind speed, and could vary with sampling location as well as particle size. The inlet was essential for comparison of coarse particle size distributions measured on the tower sites to those measured at ground level. The sample line to the Climet was made to be straight as possible, with an isokinetic flow split, to ensure representative sampling of the particles that penetrate the PM10 inlet. Transport flow to the LASAIR counter is supplied by the SMPS system, thereby minimizing gravitational and diffusional losses to this counter. 3.

Health and Safety Warnings 4.1. Laser The LASAIR contains a HeNe laser, and exposure to the direct or scattered laser light should be avoided. 4.2. Radioactive Source The TSI SMPS contains a Kr85 radioactive source. 5. Cautions The pump for the CPC should be exhausted outside, well away from any hydrocarbon canister samplers. None. 6. Interferences 7. Personnel Qualifications The system requires a technically experienced operator who understands the system, its operation and calibration. This operating procedure assumes the operator can properly use flow standards and is familiar with computer operations. Inlet consisting of: 8.
