- Collection efficiency precisely matches ISO/CEN 7708:1995 size-selection criteria
- Respirable PPI Samplers meet specifications in the 2013 OSHA NPRM for silica
- Economical and reusable – use with any suitable 37-mm filter
- Load with disposable pre-oiled impaction substrates
- Reduce particle bounce and buildup effects
- Only 3.3 ounces (93.6 grams) – ideal for both personal and area sampling
- 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 proposed lower OSHA PEL for silica
- 4 L/min respirable PPI: Enhances sensitivity and can be used with personal pumps
- 2 L/min respirable PPI: Standard TWA sampling
- 2 L/min thoracic PPI: Metalworking fluids (NIOSH Method 5524) and thoracic TLV-TWA compounds such as sulfuric acid and cotton dust
- 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
- Reusable aluminum PPIs are available
- Performance published in Journal of Physics and submitted to OSHA docket on silica
