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

thoracic TLV

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.
