SKC are proud to launch a new disposable thoracic sampler ideal for complying with the EU Workplace Exposure Limit for sulphuric acid mist.

ppisHSM 215 x 168

In 2011 a new exposure limit was introduced which specified that samples taken must be in the thoracic size, rather than inhalable. In order to comply with this requirement, the Health & Safety industry has been seeking a thoracic sampler which doesn’t break the bank but gives reliable results, every time.

The SKC disposable Parallel Particle Impactor (PPI) is precisely engineered to match the convention curve for thoracic sampling better than any other sampler on the market. Available non-loaded or in a ‘plug-&-play’ model preloaded with filters and designed for single use, you can use our disposable PPI with any standard air sampling pump to take samples for analysis. It is also available in high-flow respirable models, ideal for taking samples of respirable particulates where increased sensitivity is required - such as for respirable crystalline silica.

Tested in the UK and USA, the disposable PPI is proven to be a simple and economic answer to thoracic and respirable particulate matter sampling.

  • Collection efficiency precisely matches PM criteria
    • Independent of collected particle type
  • Contain pre-oiled impaction substrates 8 L/min respirable
    • Retain large particles
    • Reduce particle bounce and buildup effects
  • 8 L/min respirable model
    • Referenced in MDHS 14/4
    • Enhanced sampling sensitivity for silica and other compounds with low target concentrations
    • Ideal for monitoring worker exposure to silica in  hydraulic fracturing operations
    • Provides for short-term task monitoring for compounds with respirable WEL
  • 2 L/min respirable model
    • Standard TWA sampling of compounds with respirable WEL
  • 2 L/min thoracic model
    • Referenced in MDHS 14/4
    • Sulphuric acid as per EH40, metal working fluids as per NIOSH 5524, or other compounds with thoracic limits such as cotton dust
  • 4 L/min Respirable model
    • Provides higher flow option
  • Disposable PPIs are available pre-assembled with:
    • Filter, supports, and substrates for chemical analysis
    • Substrates only - add your own filter and support for gravimetric analysis

The PPI 4-in-1 Advantage

Only the patented* SKC Parallel Particle Impactor (PPI) features the power of four impactors in one small sampler to provide the closest match to the ACGIH®/ISO/CEN thoracic or respirable conventions. Each of the four impactors features its own inlet nozzle and exit orifice appropriately sized to achieve a designated cut-point. The performance of each impactor matches a segment of the sampling convention so that overall sampler performance matches the entire selected curve.
* U.S. Patent No. 7,073,402

 

The Disposable PPI Advantage

The SKC Disposable PPI combines the performance of reusable aluminium PPI models with the convenience of a single-use sampler.
