Single-use Disposable PPI Samplers are impaction-based samplers that provide a precise match to ISO 7708/CEN size-selection criteria that is specified in the 2016 OSHA final rule on respirable crystalline silica. All Disposable PPI Samplers contain pre-oiled impaction substrate that effectively trap larger particles for sample integrity. Disposable PPI Sampler models are offered for use at 2, 4, or 8 L/min and are available empty or preloaded.
Features
- Collection efficiency precisely matches ISO 7708/CEN criteria adopted in the OSHA final silica rule
- Single use means no cleaning or two-way shipping costs!
- Anti-static plastic
- Selection of flow rates available to meet specific applications
- 8 L/min respirable PPI: Enhances sensitivity (for short-term and/or low concentration sampling) using high flow pumps; ideal for new lower OSHA PEL for silica
- 4 L/min respirable PPI: Enhances sensitivity and can be used with personal pumps; TWA sampling for > 4 hours
- 2 L/min respirable PPI: 8-hour TWA sampling
- Disposable PPI Sampler Options
- Preloaded
- with filter preweighed by SKC
- with filter not preweighed
- Empty for filter loading by a laboratory or the user
- All disposable PPI Samplers are preloaded with pre-oiled impaction substrates in the inlet section
Reusable aluminum PPIs
are available

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. |
