Page 49: Appendix C Filters And Weighing Procedure
Appendix C Filters and Weighing Procedure For exact compliance with EPA PM procedures, refer to 40 CFR Part 50, Appendix L, and Section 2.12 of EPA's Quality Assurance Handbook. Filters The filter should have the following characteristics: Size: Circular, 46.2 mm diameter ± 0.25 mm. Medium: Polytetrafluoroethylene (PTFE Teflon), with integral support ring.
Page 50 Filter Cassette Handling The filter cassettes provided for use with the PQ200 are as specified in 40 CFR 50 Appendix L, Figures L-27 through L-29. The upper and lower halves of the cassette have been designed with an interference fit to prevent the cassette from coming apart easily, therefore some care must be exercised when opening and closing the cassette, especially when a filter is inside.
Page 51: Appendix D Dip Switch Functions
Appendix D Rev T Dip Switch Functions (Obsolete) There is an 8-pole dip switch located on the left side of the main control board of the PQ200, in Figure 9 of this manual. When standing in front of the PQ200, with the front panel swung forward for inspection, the dip switch will be found to the lower left, on the board.

Page 54: Appendix E Use Of The Pq200 As A Pm
Appendix E Use of the PQ200 as a PM Designated Reference Sampler The PQ200 is an EPA designated reference sampler for PM and PM sampling. To perform PM sampling, the PM adaptor should be used instead of the VSCC. The PM adapter is merely a continuation of the 12-inch long straight tube connecting the inlet to the instrument.
Page 55: Appendix F Solar Panel Power Supply
Appendix F Solar Panel Power Supply Introduction The 188095 solar panel kit is intended to permit the PQ200 to run for extended or indefinite periods of time depending on the available solar radiation at a given location. Because of the low current draw, The PQ200 is highly amenable to this technique.
Page 56 There are other factors which will reduce the energy replenishment of the system and make accurate performance predictions difficult. Amongst these are: 1. Dirt on the solar panel 2. Extreme cold weather affecting battery performance 3. Extremely high particulate loadings causing high filter resistance and consequent high current drain 4.
Page 57 The other wire emanating from the box is equipped with a CPC connector. This wire is installed through the hole in the bottom of the PQ200 enclosure normally used for the power supply cable. This wire is installed in place of the power supply cable when running on solar power. Overall Operation and Troubleshooting Prior to deploying a PQ200 with solar panel, it is prudent to ensure that the internal battery is fully charged.
Page 62: Appendix G Accessories
Appendix G. Accessories Cassette Opener (CO1) In order to prevent filter damage due to dropping or touching the filter during the cassette disassembly procedure a cassette opener has been developed to provide a gentle opening action while keeping all components on the bench top.

Both concentration measurements are to be taken simultaneously and reported on a volumetric basis, i.e. under actual (ambient temperature & barometric pressure) rather than standardized conditions.
Page 78 3. Data Reporting. Report concentrations to EPA as µg/m , at actual volume. Typically PM methods are reported in standard volume, however when sampling with two PQ200s for , both sample volumes are coarse reported in actual volumes. It is strongly recommended that you check to see the start and stop times of the PM and PM collocated PQ200s are within 15 minutes of each other.
Page 79 Appendix M Leak Test Procedure for S/Ns 906 through 1016 On September 01, 2010 BGI changed the PQ200 External Leak Check procedure for Serial Numbers greater than S/N906. The electronic Solenoid Valve was removed and replaced with a manual valve to perform the external leak check procedure.
Page 80 After 10 to 15 seconds the SP will rise to approximately 95 cm. When the SP reading displays 95 cm, “immediately” close the Leak Test valve near the filter holder by rotating the handle forward to the 9 o’clock position. After two seconds the screen will display LEAK TEST IN PROGRESS and the SP display should remain constant at a SP number of 95 to 100 cm.

Page 85 Appendix O WINS Installation (Obsolete) • To open the WINS (Well Impactor Ninety-Six) and filter assembly inside the PQ200 sampler case, carefully rotate the handle counterclockwise using both hands. (CAUTION! Once the assembly has started to open, the weight of the two plates will tend to force the whole assembly open even further.) This will expose the WINS impactor and the filter cassette (see Figure 4).
Page 86 impactor well is in good condition and maintains a tight fit. Replace if necessary. Wipe the exterior of the well with a clean Kimwipe. Transport the well to the sampler upright in a clean, protective container away from direct sunlight or extreme temperatures.
Page 87 Appendix P Pump Rebuild Instructions 1. 1.0 Introduction The pump used in the BGI PQ100 and PQ200 air samplers is of Mesa design and manufacture. The only items not of Mesa manufacture are the motor and bearing for the eccentric. The basic design is a double diaphragm, steel reed valve, scotch yoke.
Page 88 2. 3.0 Disassembly and Inspection All of the component parts of the pump are shown in Figure P1 and described in the parts list, Table 1. Four levels of repair/rebuild kit are made available. Other than the parts listed in the kits, it is not anticipated that any other components will be required except through physical damage or loss.
Page 89 Step 1: To start rebuilding your pump, remove the two screws that secure the motor to the pump body. The motor assembly can now be pulled away from the pump body. Inspect the eccentric bearing for looseness on the shaft. Inspect the bearing for smooth rotation and absence of play.
Page 90 lines on the face containing the motor or the mounting studs. If the motor also requires replacement after removing the eccentric bearing assembly, also remove the three motor plate screws which secure the motor plate to the motor. The new motor is attached to the plate utilizing the three screws just removed.
Page 91 3.4 Diaphragm Removal Step 6: The diaphragms are removed by grasping the diaphragm retainer between the thumb and forefinger and rotating in a counter- clockwise direction when looking down at it. The other hand is used to grasp the same component on the opposite side.
Page 92 the moment. Prepare the opposite diaphragm assembly and screw it into the yoke, holding each assembly between the thumb and forefinger of each hand. Each diaphragm may now be inserted into its respective recess. The edges of the disks are to be tucked into the recess in the pump body.
Page 93 before the pump “turns over”. This is within normal limits but should only occur, if at all, during the first start up. If 30 seconds has been exceeded, shut down at once. The assembly procedures have not been correctly followed. If the pump runs but there is little or no air flow, check to ensure that one of the valve assemblies has not been reversed.
