INTRODUCTIONS |
|
The Model 310 Universal Air Sampler™ (UAS™) is a general purpose air sampler for atmospheric aerosol sampling and for mass concentration, and organic or inorganic analysis. The sampler has a design inlet sampling flow rate of 300 Liters per minute (Lpm). Fully equipped, it includes two virtual impactors for size fractionation of airborne particles and a Poly-Urethane Filter (PUF) sampler for analysis of volatile organic compounds (VOCs) in the air sample. The sampler is provided with an omni-directional inlet, a PM10 (10 μm cut) virtual impactor classifier, either a PM2.5 or PM1.0 virtual impactor classifier, a fine particle filter and a PUF sampler. This allows operation as a high volume dichotomous sampler for size fractionation of airborne particles in the 0-2.5 μm (0-1.0 μm) and 2.5-10 μm (1.0-10 μm) aerodynamic size ranges. When only one virtual impactor is installed, it can be operated as a PM10, PM2.5 or PM1.0 sampler, depending on the cut point diameter of the classifier used. |
