INTRODUCTION
The SKC DPS System is a compact, portable, battery-operated, and cost-effective
particulate sampling system that ensures the ability to monitor particulate matter
(PM) in indoor and outdoor environments and in urban, industrial, or rural settings.
The system features the fully programmable constant flow Leland Legacy® Sample
Pump, the IMPACT Sampler, and other equipment needed for effective 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 specific cut-point (2.5 μm or 10 μm) by
capturing them on a disposable oiled impaction disk that reduces particle bounce.
Particles smaller than the cut-point are collected on a 47-mm filter. The IMPACT
Sampler mounts easily and makes media changes fast and simple with its convenient
removable filter cassette and opener.

PRINCIPLE OF OPERATION
A sample pump draws particle-laden air at a flow rate of 10 L/min through an inertial 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 flow rate causing eight airjets to impinge
onto the impaction disk positioned below the inlet nozzles. Particles larger than
the sampler cut-point with enough inertia to cross the airstream lines impact on
the impaction disk. The airflow, containing smaller particles, makes a sharp turn,
passes through the openings in the top of the filter cassette, and follows through
to a 47-mm filter where the smaller particles collect.
The top of the filter cassette accommodates the impaction disk. For optimum impactor performance, a 37-mm oiled porous plastic disk is recommended as disposable
collection substrate (supplied with system). If chemical analysis of larger particles
is desired, a 37-mm filter (quartz or PTFE) may be used.

MEDIA PREPARATION
Collection Filters: Equilibrate and pre-weigh filters in a clean environment
according to appropriate procedures. Record the weight as the pre-sample
weight.
Impaction Disk: Ready-to-use pre-oiled disposable plastic impaction disks are included
with the system (qty. 25). Replacement pre-oiled plastic disks are available as SKC
Cat. Nos. 225-395 (qty. 25) and 225-395A (qty. 50). Using an oiled impaction disk
reduces particle bounce.
37-mm filters (quartz or PTFE) may be used if chemical analysis of larger particles is desired.
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 cassette 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.
Do not place any mechanical object in the inlet nozzles.
O-ring Care
Visually inspect the condition of the BUNA-N exhaust O-ring (see illustration on
page 3 for location). Ensure the O-ring surface is smooth (i.e., without cracks, cuts,
or other damage). Ensure the O-ring is fitted properly in its channel. Replace the
exhaust O-ring if there is apparent damage, stretching, or thinning. It is recommended that the PTFE inlet O-ring be replaced by the manufacturer only.

Inserting a Collection Filter into the IMPACT Sampler
The IMPACT Sampler will arrive already assembled. Disassemble it to insert
collection filter.
1
Unscrew inlet from exhaust.
Remove filter cassette.
Ensure the stainless steel support
screen is in place in the bottom of the
filter cassette.
3a. Use the filter cassette opener
to open filter cassette.
3b. Slide the filter cassette horizontally into the “U” of the opener
until the two halves of the cassette loosen. Gently pull halves
apart.
Using forceps, place a preweighed
47-mm filter on the support screen.
Press filter cassette top into filter
cassette bottom.
Technical Tidbit

7
Reinsert cassette into impactor.
5
Use forceps to carefully
insert or remove the
collection filter. See
Accessories for forceps.
Inserting an Impaction Disk into the IMPACT Sampler
For PM2.5 or PM10 sampling, insert an impaction disk only after a collection
filter has been loaded into the filter cassette.
For PM2.5 or PM10,
ensure a collection filter
has been loaded into the
filter cassette (see Inserting
a Collection Filter into the
IMPACT Sampler).
1
Place impaction disk in recessed area on filter
cassette top. The rough side of the impaction disk
should face up. SKC-supplied disks are stamped
with “UP” on the appropriate side.
Keep sampler upright until the inlet is
securely screwed onto the exhaust to
prevent the impaction disk from being
dislodged.
Place filter cassette on exhaust and screw
impactor inlet and exhaust together just until
tight. Further hand-tighten by 1/4 turn only.
Do not overtighten impactor inlet and
exhaust. Do not use barbed fitting as leverage when tightening.
Technical Tidbits
•
Install the rain cover (included with the DPS System) on the inlet of the
IMPACT Sampler when sampling outdoors.
•
SKC recommends using a new impaction disk for each sample.
6
SAMPLE PUMP OPERATION
The user may choose to operate the pump manually in the
field (on/off ), program a schedule into the pump manually,
or program the pump for multiple schedules from a PC with
optional DataTrac® for Leland Legacy Software (see Ordering
Information, Accessories).
See page 10 for a Quick Guide for operating the SKC Leland
Legacy Sample Pump. For advanced programming, see the
complete Leland Legacy Pump Operating Instructions.
Charging the Battery
Completely charge a new battery pack using the SKC-approved charger (Cat. No.
223-241) before operating the pump. It may be necessary to charge the battery a
few times before maximum battery capacity is achieved.
Cautions:
• Do not charge or operate pump with or without charger in hazardous
locations.
• Use only the SKC-approved charger for this pump. Use of an unapproved
charger may damage the battery and pump.
• Use of a non-approved charger voids any warranty.
• Do not open, disassemble, short circuit, crush, incinerate, or expose the
battery to fire or high temperatures.
• Tampering with the battery pack voids any warranty.
• Ensure proper orientation of charging cable before plugging it into the
charging jack. Improper orientation/contact will short-circuit the battery
and voids any warranty.
• Short-circuiting the battery pack will render it immediately inoperative.
• Failure to follow warnings and cautions voids any warranty.
The battery pack may be kept on the SKC-approved charger for an
indefinite time.
1. Insert the plug from the charging unit into the
charging port on the battery adapter (on top of
the external battery assembly).
2. Insert plug from power supply into the jack on
the charging unit.
3. Install the appropriate wall plug on the power
supply and plug power supply into a power outlet.
The battery will recharge in approximately 15
hours. For a complete charge, do not run the
pump connected to the external battery assembly

during charging. After charging is complete, disconnect battery from charger and
connect pump to battery (see Battery Setup).
After charging the battery pack, it is good practice to run the pump for
approximately 5 minutes before calibrating. This ensures the battery is in
more steady-state conditions and improves the agreement in pre and postsampling calibrations.
Reading the Charging Status LED
