SKC Preloaded Disposable Parallel Particle Impactor Operating Instructions Manual page 2

Performance Profi le
Sampling Rate: 2 L/min respirable or thoracic, 4 or 8 L/min respirable
Sample Pump: • Universal XR or AirChek
• 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 aff ect
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/m
and equals 50% of total dust. However, labs have reported to SKC that they
prefer no more than 2 mg on the fi lter for analytical reasons. Therefore,
SKC recommends that you work with your lab to determine optimum
sample times for your unique sampling conditions.
