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

Automated Mercury Speciation 2 Model 1135 – Particulate Mercury Monitor Unit stacks on top of Model 1130 Unit stacks on top of Model 1130 Allows simultaneous deter- mination of Hg 0, RGM and Hg P Allows simultaneous deter- mination of Hg 0, RGM and Hg P Detection limit < 2 pg/m 3 Detection limit < 2 pg/m 3

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

Automated Mercury Speciation 4 Data Characteristics High time resolution Hg 0 data provided during sampling phase High time resolution Hg 0 data provided during sampling phase  Typically every 2½ or 5 min  Data is averaged to yield one Hg 0 point per sampling period Single RGM integrated value every sample 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 Data values are for the exact same time period
