  1. Detailed Operation: Model 1130 and Model 1135 Rev: 1.11 November 3, 2003

  2. Model 1135 – Particulate Mercury Monitor • Unit stacks on top of Model 1130 • Allows simultaneous deter-mination of Hg0, RGM and HgP • Detection limit < 2 pg/m3

  3. Instrument Characteristics • Fully automated, unattended operation • Denuder exchanged every 1 or 2 weeks • Operates in any environment • Polar (Greenland, USA, Canada, Antarctica) • Sub-tropical (Florida Everglades) • Desert (Nevada) • Marine (ocean cruises) • High altitude (Mauna Loa)

  4. Data Characteristics • High time resolution Hg0 data provided during sampling phase • Typically every 2½ or 5 min • Data is averaged to yield one Hg0 point per sampling period • Single RGM integrated value every sample period • Sample period: 0.5 – 3 hours • Analysis Period: 25 – 60 min • Data values are for the exact same time period

  5. Zero Air Inlet Sample Air Inlet Elbow (not used with 1135) Annulus Coupler Coupler Elutriator Jet Impactor Body & Disk Quartz Denuder Assembly

  6. Tail Quartz Wool Pyrolyzer (quartz chips) Air Gap Quartz membrane filter disk Quartz Wool Inlet (from denuder) RPF • Quartz wool captures bulk of particulate matter • Quartz filter membrane provides sharp cut-off (<0.1 um) • Built in pyrolyzer section converts desorbed species to Hg0 • Carbon based particulate matter on the filter is oxidized to CO2 during desorption cycle • Tail provides cooling

  7. Analytical Sequence • Wait state is entered whenever: • Model 1130 or Model 2537A is first started up • Model 2537A goes into Idle or Calib mode • Wait state is exited and monitoring cycle begins when: • Model 2537A is in Run mode, and • Cycle transition is detected

  8. Typical Flow Rate Settings

  9. Analytical Functions

  10. Event Flag Assignments

  11. Typical Temperature Settings • Temperatures are set directly on the PID controllers • System simply selects between the two set-points on analytical PID controllers • Case temperature controllers independently actuate either: • case heater, or • cooling fan

  12. Method Calculated Values • Values are calculated both by the controller and by XLS spread sheet • Most are for info only • Factors must be entered into 2537A to ensure direct reading in pg/m3

  13. Step 0: Sample

  22. Operation

  23. Installation Requirements • Location • Need outdoor location within 25 ft. of 2537A • Fetch is very important • Vertical height. Should be 3-10 m above grade • Power requirements (when desorbing only) • Approx. 1200 VA required by Model 1130 • Further 1300 VA required by Model 1135 • Two dedicated standard 115 VAC 15A circuits • Pump module can share circuit with 2537A

  25. Operational Requirements • Denuder requires changing every week or two • RPF requires exchanging every 8 to 12 weeks • Weekly or bi-weekly site visits recommended • Filter changes, leak checks, etc. as required during site visits

  26. Lab Support • Extra denuders & RPF’s are usually kept on hand • Several units recoated / restuffed at one time • Blanked, capped and shipped to site • Tube furnace required for blanking • Source of DIW is required • Elements may be exchanged in the field using relatively unskilled personnel
