3. Insert collection fi lter in fi lter cassette.

4. Press prepared impaction disc into top of fi lter cassette.

5. Reinsert fi lter cassette in impactor.

6. Reassemble impactor.

Sampling Setup and Calibration

1. Set up sample pump. Set pump fl ow rate to 10 L/min. (See Leland Legacy Quick Guide on
page 10. For advanced programming, see Leland Legacy Operating Instructions.)

2. Screw calibration adapter onto impactor.

3. Use tubing with quick-connect to attach pump inlet to outlet of impactor. Use short tubing to
connect inlet of calibration adapter to outlet of calibrator to form a calibration train. Calibrate
pump fl ow rate with calibrator. Record fl ow rate. Reset accumulated data if required.

4. Disconnect calibrator and remove calibration adapter from impactor. Remove calibration
media and place new unexposed media in impactor.

5. Mount bracket at desired location.

6. Screw impactor onto mounting bracket.

7. Screw rain cover onto impactor.

Sampling

1. Turn on pump and record pertinent data. (Leland Legacy pump may be started manually or
automatically, see Quick Guide on page 10.)

2. Turn off pump after desired sample time has elapsed. Record pertinent information.

3. Remove rain cover, reinstate calibration train, and verify pump fl ow rate.

Sample Removal

1. Use quick-connect to detach tubing from pump.

2. Disassemble impactor.

3. Remove impaction disc.

4. Remove fi lter cassette, disassemble, and remove collection fi lter.

5. Place collection fi lter in appropriate container for shipping.

INTRODUCTION

The SKC DPS System is a compact, portable, ba ery-operated, and cost-eff ective
particulate sampling system that ensures the ability to monitor particulate ma er
(PM) in indoor and outdoor environments and in urban, industrial, or rural se ings.
The system features the fully programmable constant fl ow Leland Legacy
Pump, the IMPACT Sampler, and other equipment needed for eff ective ambient
PM10 or PM2.5 sampling. All components are packaged in an easily carried heavy­duty Pelican

®

case from which the system operates.

The heart of the DPS System is the patented* IMPACT Sampler. This inertial impactor
is designed to remove particles larger than a specifi c cut-point (2.5 μm or 10 μm) by
capturing them on a disposable oiled impaction disc that reduces particle bounce.
Particles 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 and opener.

PRINCIPLE OF OPERATION

A sample pump draws particle-laden air at a fl ow rate of 10 L/min through an in-
ertial impactor to separate airborne particles according to aerodynamic diameter.
Particles enter the impactor through eight nozzles on top of the sampler. The inlet
nozzles are sized to operate at a 10 L/min fl ow rate causing eight airjets to impinge
onto the impaction disc positioned below the inlet nozzles. Particles larger than
the sampler cut-point with enough inertia to cross the airstream lines impact on
the impaction disc. The airfl ow, containing smaller particles, makes a sharp turn,
passes through the openings in the top of the fi lter casse e, and follows through
to a 47-mm fi lter where the smaller particles collect.

The top of the fi lter casse e accommodates the impaction disc. For optimum impac-
tor performance, a 37-mm oiled porous plastic disc is recommended as disposable
collection substrate (supplied with system). If chemical analysis of larger particles
is desired, a 37-mm fi lter (quartz or PTFE) may be used.
