The unique, patented SKC Parallel Particulate Impactor (PPI) Samplers are impaction-based and provide a precise match to ISO/CEN size-selection criteria. Respirable PPI Samplers match ACGIH and the ISO 7708/CEN criteria that is specified in the 2016 OSHA final rule on respirable crystalline silica. SKC PPI Samplers are offered in a choice of flow rates for maximum flexibility in pump options, sample duration, and contaminant concentration. PPI Samplers are available in disposable single-use plastic or reusable aluminum.
Features
- Collection efficiency precisely matches ISO 7708/CEN
criteria adopted in the OSHA final silica rule
- Resusable conductive aluminum
- 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
- Patented disposable PPIs are
available pre-assembled with:
- Filter and pre-oiled substrates for chemical analysis
- Pre-oiled substrates
only – add your own weighed filter for
gravimetric analysis
- Performance published in Journal of Physics and referenced in the OSHA final silica rule
