IMPACT Sampler

The patented* IMPACT Sampler is an inertial impactor designed to remove particles

larger than its cut-point by capturing them on a disposable oiled impaction disc that

reduces particle bounce. Particles that are smaller than the cut-point are collected on

a 47-mm ﬁ lter. The IMPACT Sampler mounts easily and makes media changes fast

and simple with its convenient removable ﬁ lter casse e.

The IMPACT Sampler is also part of a cost-eﬀ ective portable particulate sampling

system that ensures the ability to monitor particulate ma er in indoor and outdoor

environments and in urban, industrial, or rural se ings (see Ordering Information for

details on the DPS System or visit www.skcinc.com/prod/100-3901.asp).

Principle of Operation PM10 inlet PM2.
PAGE 3
Impactor Preparation Cleaning For optimum performance, the IMPACT Sampler inlet, exhaust, and filter cassette should be cleaned after five runs or upon a noticeable buildup of material. This will remove oil buildup from the top of the filter holder and other residue built up from frequent sampling. Disassemble the impactor and wash parts in water with a liquid detergent or soap. Rinse and air-dry all parts thoroughly in a clean environment. Caution: Do not place any mechanical object in the inlet nozzles.

When sampling for PM Coarse using the Coarse Ring accessory or IMPACT PM Coarse Sampler, no collection filter or stainless steel support is inserted in the first filter cassette. Insert a 47-mm collection filter into the second filter cassette (refer to illustration on page 2). Proceed to Inserting an Impaction Disc into the IMPACT Sampler. 7 Reinsert cassette into impactor. Inserting an Impaction Disc into the IMPACT Sampler For PM2.
PAGE 5
Calibration and Sampling Note: As the particle load on the filter increases during sampling, the pressure drop will also increase. Therefore, use a compensating sample pump such as the Leland Legacy® (SKC Cat. No. 100-3002). The Leland Legacy pump will provide 24 hours of run time at 10 L/min at a maximum pressure drop of 12 inches water. Calibration Calibrate pump flow rate with the IMPACT Sampler in line (loaded with filter and impaction disc). See pump and calibrator operating instructions.

Sampling 1. If required, replace representative sample media used for calibration with new, preweighed media (see Media Preparation and Impactor Preparation). 2. Mount bracket accessory at the desired location and at breathing zone height (6 feet or 2 meters) using wire ties or other fasteners. Mount impactor on mounting bracket accessory by threading clamp knob into bottom of impactor. 3. Insert screw on rain cover into screw hole in top of impactor inlet and rotate cover until tight. 4.

Sample Removal, Shipping, and Analysis Removing the Collection Filter and Impaction Disc 1 Locate recessed area on filter cassette top and remove impaction disc. If chemical analysis of larger particles is desired, place in appropriate container for shipping to a laboratory for analysis (see Ordering Information, Accessories for Glass Jars). Unscrew impactor inlet from exhaust. 3 4 Gently lift filter cassette from exhaust. 4a. Use the filter cassette opener to separate the two halves. 4b.
