Overview
This plastic Disposable PPI® Sampler features four impactors arranged in parallel for precise respirable dust sampling at 8 L/min that meets ISO 7708/CEN respirable criteria. It is preloaded with four porous plastic disc impaction substrates, one 37-mm 5.0-µm PVC collection filter, and one cellulose support. The red color identifies it as an 8 L/min respirable model. Single use.
Impaction-based respirable model user-loaded Disposable PPI Samplers contain four impactors arranged in parallel that provide the most precise match to the entire ISO 7708/CEN respirable criteria. Listed in OSHA and MSHA Final Silica Rules, PPI Samplers are also ideal for NIOSH respirable dust methods. All Disposable PPI Samplers contain pre-oiled impaction substrates that effectively trap larger particles for sample integrity. Their design eliminates the tipping sample invalidation often experienced with cyclones, saving you time and money. Disposable PPI Samplers are offered for use at 2, 4, or 8 L/min to meet your applications and are available empty or preloaded. Preloaded models are available with filter preweighed by SKC or not preweighed. Preloaded PPI Samplers do not require assembly. The disposable plastic is single use, so no cleaning is required.

Performance Profile

Sampling Rate2, 4, or 8 L/min
Sample PumpAirChek Series for 2 and 4 L/min, Leland Legacy for 8 L/min
Sample TimeDependent 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. Some methods specify 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.
