URG 9000A Ambient Ion Monitor Brochure

URG 9000 SeriesAmbient Ion MonitorMeasurement CapabilitiesThe 9000 Series Ambient Ion Monitors consist of four configurations. The URG-9000A Ambient Ion Monitor (AIM) provides time-resolved direct measurements of anion particulate Nitrate, Sulfate, Nitrite, Phosphate and Chloride found in PM-2.5. Nitrite and Sulfate aerosols are produced as a result of the interaction of ammonia (NH3), NOx, SO2 and other gaseous constituents. These ions can represent a significant portion of the PM-2.5 and are important in understanding visibility degradation, atmospheric chemistry and inputs into various ecosystems. The URG-9000B Ambient Ion Monitor (AIM) has an additional Ion Detector to allow for time-resolved direct measurements of cation particulate Ammonium, Sodium, Calcium, Potassium and Magnesium in addition to the anion particulate. The URG-9000C Ambient Ion Monitor (AIM) provides time-resolved direct measurements of anion gases Hydrogen Chloride, Nitric Acid, Nitrous Acid and Sulfur Dioxide in addition to the anion particulate. The URG-9000D Ambient Ion Monitor (AIM) provides time-resolved measurements of ammonia in addition to the anion gases, anion particulate and cation particulate.Sample CollectionThe AIM Monitor incorporates several state-of-the-art components for sample collection. It draws air in through a PM-2.5 sharp-cut cyclone at a volumetric-flow controlled rate of 3Lpm to remove the large particles from the air stream. The sample is then drawn through a Liquid Diffusion Denuder where interfacing acid gases are removed. In order to achieve high collection efficiencies, the particles-laden air stream next enters the Aerosol Super-Saturation Chamber to enhance particle growth. An Inertial Particle Separator collects these enlarge particles, which are then injected into the Ion Chromatograph. Both particles and gases are collected and injected using syringe pumps, PEEK valves, Teflon® tubing and PEEK tubing.The sampler can collect and analyze up to 10 days unattended. This period can be extended, if necessary, by using larger solution reservoirs.URG-9000C with Reagent FreeIon ChromatographEnlarged View of Liquid Diffussion DenuderAnalysis MethodThe analysis method for the AIM Monitor is Ion Chromatography. An AIM Monitor requires as little as 4 liters of deionized water for 10 sampling days. The detection limit is 0.05ug per cubic meter and can be less depending on which ion is being measured.The Ion Chromatography separates the nitrate and sulfate ions, so that the measurements are not affected by other nitrogen-containing compounds. Losses due to volatilization are eliminated because the particles are collected in a solution and then analyzed by Ion Chromatography. All the AIM Monitors include chemical suppression Ion Chromatographs (IC). The ICs on any of the AIM Monitors can be upgraded to the options below:IC Options:Electrolytic Suppression ICReagent Free ICURG-9000D with Reagent FreeIon ChromatographAmbient Ion Monitor SpecificationsPower: 115VAC or 220VACDimensions: 19” x 16” x 36”Weight: 65-85 lbs.Measures: Nitrate, Sulfate, Nitrite, Phosphate, Chloride, Ammonium, Sodium, Calcium, Potassium, Magnesium, Ammonia Hydrogen Chloride, Nitric Acid, Nitrous Acid and Sulfur DioxideDetection Limit: 0.05 ug/m3 Every Hour(Optional 15-30 Minutes)Installation: Requires Installation in an Environmentally-Controlled Shelter Where The Temperature is Maintained Between 20-30 Degrees CelsiusConfigurations: Stand-Alone or Rack Mountable Unit AvailableThe Ambient Ion Monitor uses a Windows-based program to display and store the data. The analyte data is displayed in micrograms per cubic meter. The ambient temperature and barometric pressure are also displayed and recorded.Ordering InformationURG-9000A - Time-Resolved Direct Measurements of Nitrate, Sulfate, Nitrite, Phosphate and ChlorideURG-9000B - Time-Resolved Direct Measurements of Nitrate, Sulfate, Nitrite, Phosphate, Chloride, Ammonium, Sodium, Calcium, Potassium and MagnesiumURG-9000C - Time-Resolved Direct Measurements of Nitrate, Sulfate, Nitrite, Phosphate, Chloride, Hydrogen Chloride, Nitric Acid, Nitrous Acid and Sulfur DioxideURG-9000D - Time-Resolved Direct Measurements of Nitrate, Sulfate, Nitrite, Phosphate and Chloride, Ammonium, Sodium, Calcium, Potassium, Magnesium, Hydrogen Chloride, Nitric Acid, Sulfur Dioxide and AmmoniaAmbient Ion Monitor with Laptop(Comes Standard with PC Computer)
