Denuder System

URG announces the Annular Denuder System.

This system collects both acidic and basic gases with little or no interference from sampling artifacts and concentrates samples for characterization by analytic methods.

A variation on the ADS includes the Versatile Air Pollutant Sampler, which allows the simultaneous measurement of a variety of air quality parameters. Other variations include the Dual Channel Sequential Fine Particle Sampler and the Weekly Air Pollutant Sampler, which collect aerosols, semivolatiles, and mass in a preset time sequence.
