IMPACT Sampler Impactor, PM Coarse

Part Number:

225-3911

Overview

IMPACT Sampler, two-stage inertial impactor for 10 L/min ambient PM Coarse (PM10-2.5) sampling, includes filter cassette (holders), calibration adapter, rain cap and PM Coarse Ring (Cat. No. 225-3912); suitable for use with sampling pumps operating at 10 L/min.

Details

Patented IMPACT Samplers are single-stage inertial impactors that sample PM10, PM2.5, or PM Coarse (10-2.5) at 10 L/min in ambient air. The higher flow rate provides increased sampling sensitivity, making it ideal for environmental PM sampling and indoor air studies. The IMPACT’s removable filter cassette and disposable pre-oiled impaction discs make it fast and easy to deploy (no cleaning or greasing). IMPACT is the sampling head in the SKC Deployable Particulate Sampler (DPS) System. SKC recommends using IMPACT with the Leland Legacy® Sample Pump.
