SKC Re-usable Parallel Particle Impactors (PPI)
The patented
†
impaction-based SKC Re-usable Parallel Particle
Impactor (PPI ) Samplers are designed to match precisely the
collection effi
ciency curves for respirable and thoracic dust
specifi ed by ISO/CEN 7708:1995 and adopted by ACGIH,
CEN, and other occupational hygiene organizations. The
performance of the respirable PPI samplers also meets
the specifi cations in the 2013 OSHA Notice of Proposed
Rule Making (NPRM) for respirable crystalline silica. The
thoracic model meets the requirements of NIOSH Method
5524 for metalworking fl uids and compounds with ACGIH

s. Constructed of conductive aluminum, these
PPI Samplers may be re-used and off er a choice of fl ow rates
for maximum fl exibility in pump options, sample duration,
and contaminant concentration.
