PPWD (Model 9100)

Semi-Dry EC (Model 9200)
PILS(Model 9300)

Applications :

• Clean Room Airborne Acid/Basic Molecular contaminant Monitoring
• Ambient Aerosol (PM 2.5/10) and Acid/Basic Gas Monitoring
• Stack Acid/Basic Gas Monitoring
• R&D

Features :

• Direct Measurements of Nitrate, Sulfate, Nitrite, Phosphate and Chloride, Sodium, Ammonium, Calcium, Potassium, Magnesium, Hydrogen Chloride, Nitric Acid, Sulfur Dioxide, Hydrogen Fluoride and Ammonia
• Provides a timely data stream of multi-pollutants that influence atmospheric chemistry and air quality
• Operates and collects multi-pollutant data continuously
• Provides gases and particles as time-resolved measurements
• Allows for continuous improvement in source apportionment analyses
• Helps to improve modeling necessary for determining the relative contributions of various emission sources

Description :

The principal components of the Model 9100 A/B/C PPWD and Semi-Dry EC Sampling System are de-signed by Professor Chuen-Jinn Tsai of NCTU (Taiwan Patent No: I327641), and it can be connect to any PM-10/2.5 or TSP or our Model 2000 iTMS Manifold System for multi points sampling.

Chemical Species Collected Gases :

Ammonia (NH3), Hydrogen Fluoride (HF), Hydrochloric Acid (HCl), Nitric Acid (HNO3), Nitrous Acid (HNO2 ), Acetic Acid(CH3COOH), Formic Acid (HCOOH), Sulfur Dioxide(SO2), Phosphoric Acid (H3PO4) and Other Soluble Gases.

Particulates :

Nitrate (NO3-), Ammonium (NH4+), Sulfate (SO4=), Nitrite (NO2-), Fluoride (F-), Chloride (Cl-), Phophate (PO4-) and other Cations and Anions.

Once collected, the pollutant concentrations are quantified by Ion Chromatography Analysis.
