SKC Preloaded Disposable Parallel Particle... User manual

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
support pad or 37-mm Quarfilter and cellulose support pad
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
Diameter: 1.8 in (4.6 cm)
Depth: 1.2 in (3 cm)
Weight: 1.1 oz (31.2 gm)
Shelf-life: 18 mos from date of manufacture

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.
