SKC Preloaded Disposable

Parallel Particle Impactors (PPI)

The patented†impaction-based SKC Disposable Parallel Particle Impactor (PPI®)

Samplers are designed to match precisely the collection efficiency curves for

respirable and thoracic dust speciﬁed by ISO 7708/CEN and adopted by ACGIH,

CEN, and other occupational hygiene organizations. The performance of the

respirable PPI samplers also meets the ISO 7708/CEN criteria included in the OSHA

ﬁnal silica rule. The thoracic model meets the requirements of NIOSH Method 5524

for metalworking ﬂuids and compounds with ACGIH®thoracic TLV®s. Disposable

PPI Samplers oﬀer the convenience of single use to eliminate sampler assembly and

cleaning; small size for worker comfort, even under helmets or other PPE; and a

choice of ﬂow rates for maximum ﬂexibility in pump options, sample duration, and

contaminant concentration. These instructions are for PPI models pre-assembled

with ﬁlter, support, and impaction substrates.

Preloaded ﬁlters in some models are available preweighed by SKC for gravimetric

analysis. See the table below.

Performance Proﬁle

Sampling Rate: 2 L/min respirable or thoracic, 4 or 8 L/min respirable

Sample Pump: • Universal XR or AirChek

Series for 2 and 4 L/min

• Leland Legacy for 8 L/min

Sample Time: Dependent on method used.

Note: SKC tests indicate that a particulate

mass of up to 6.8 mg on the four impaction substrates would not aﬀect

PPI performance. This amount is equivalent to sampling for 6 hours at

4 L/min in environments where respirable mass concentration is 4.76 mg/m3

and equals 50% of total dust. However, labs have reported to SKC that they

prefer no more than 2 mg on the ﬁlter for analytical reasons. Therefore,

SKC recommends that you work with your lab to determine optimum

sample times for your unique sampling conditions.

Sample Media: Respirable models: 37-mm, 5.0-μm PVC ﬁlter and cellulose

support pad

Thoracic model: 37-mm, 0.8-μm MCE ﬁlter and cellulose

Impaction Four 3/8-in diameter pre-oiled porous plastic discs

Substrate: (Assembled in all Disposable PPIs)

Analysis: Chemical or gravimetric

Body Material: Conductive ABS plastic

Dimensions: Height: 4.25 in (10.8 cm) - clip to exhaust

Principle of Operation

SKC Disposable PPI Samplers are impaction-based ﬁlter samplers that perform

precise size-selection for either thoracic or respirable dust, depending on the model.

PPI Samplers contain four small impactors in the inlet section of the device. Each

impactor features a unique 50% cut-point to target a speciﬁc one-quarter segment of

the ISO/CEN curve resulting in a precise ﬁt along the entire curve. A sample pump

operating at 2, 4, or 8 L/min (2 L/min only for thoracic) pulls air through the inlet

nozzle of each impactor in the inlet plate. Particles larger than each impactor’s 50%

cut-point are scrubbed and retained by impaction onto the porous oiled impaction

substrate contained in each impactor. Smaller particles continue to the standard

37-mm collection ﬁlter for analysis.

Sampler Preparation

SKC Preloaded Disposable PPIs are supplied assembled and ready to use.

For gravimetric analysis: PPIs 225-3841-PW, 225-3871-PW, and 225-3851-PW are

preloaded with a preweighed 5.0-μm PVC ﬁlter. If using PPIs preloaded with a 5.0-μm PVC

ﬁlter that has not been preweighed (Cat. Nos. 225-3841, 225-3871, and 225-3851), contact

your laboratory to pre and postweigh ﬁlter.

1. Remove shrink wrap.

2. Write sample ID on sampling label. Adhere sampling label to boom of

base plate.

3. Remove protective end cap from exhaust.

Calibration and Sampling

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 AirChek Series or Leland Legacy depending on ﬂow rate requirements.

Calibration

Calibrate the pump ﬂow rate with a representative Preloaded Disposable PPI

sampler. See pump and calibrator operating instructions.

1. Ensure the pump has run for 5 minutes before calibrating.

2. Ensure representative impactor is loaded with a support and collection ﬁlter

and that it is fully assembled. See Sampler Preparation above.

3. Align the boom of the calibration adapter with the inlet plate of an assembled,

loaded representative Disposable PPI and press down firmly until the

calibration adapter’s O-ring is engaged and creates an even seal.

4. Use ﬂexible tubing to connect the exhaust of the Disposable PPI to the inlet of

a sample pump.

5. Use ﬂexible tubing to connect the inlet of the calibration adapter to the suction

port (outlet) of a calibrator.

6. Calibrate to 2 L/min for the 2 L/min respirable and thoracic model PPIs,

4 L/min for the 4 L/min respirable model, or 8 L/min for the 8 L/min respirable

model. Follow the calibration instructions in the pump and calibrator operating

instructions.

7. When calibration is completed, disconnect the tubing from the calibrator and

calibration adapter.

8. Grasp the Disposable PPI with one hand and the calibration adapter with

the other hand. Firmly pull/twist to remove the calibration adapter from the

Disposable PPI inlet plate.

9. Replace the representative Disposable PPI used to set the ﬂow with a new,

unused preloaded Disposable PPI for sample collection.

Using excessive pressure to

seal the calibration adapter to

the Disposable PPI may make

the calibration adapter difﬁcult

to remove.

Sampling

SKC tests indicate that a particulate mass of up to 6.8 mg on the four impaction

substrates would not affect PPI performance. This amount is equivalent to sampling

for 6 hours at 4 L/min in environments where respirable mass concentration is

4.76 mg/m3 and equals 50% of total dust. However, labs have reported to SKC that

they prefer no more than 2 mg on the ﬁlter for analytical reasons. Therefore, SKC

recommends that you work with your lab to determine optimum sample times for

your unique sampling conditions.

1. As per good industrial hygiene practice, replace representative sampler used

for calibration with a new, unused preloaded sampler.

2. Record sample start time on label.

3. Clip Disposable PPI onto a worker’s collar or lapel in the breathing zone or in

the area to be sampled.

4. Clip sample pump at the worker’s waist or close to the Disposable PPI.

5. Use ﬂexible tubing to aach the Disposable PPI exhaust

to the inlet of the sample pump.

6. Turn on pump and record pertinent sample data.

7. After the desired sample time has elapsed, turn oﬀthe

pump and unclip sampler from sampling location.

8. Apply Post-use label to inlet plate to seal the

sampler.

9. Record sample stop time on label on the boom

of sampler.

10. Disconnect sampler from pump and reinstall

protective end cap on the exhaust.

11. Reinstate calibration train with representative

Disposable PPI and verify ﬂow rate. See Calibration.
