Parallel Particle Impactors (PPI)
The patented
†
impaction-based SKC Disposable Parallel Particle Impactor (PPI
Samplers are designed to match precisely the collection efficiency curves for
respirable and thoracic dust specifi ed by ISO 7708/CEN and adopted by ACGIH,
CEN, and other occupational hygiene organizations. The performance of the
respirable PPI samplers also meets the ISO 7708/CEN criteria included in the OSHA
fi nal silica rule. The thoracic model meets the requirements of NIOSH Method 5524
for metalworking fl uids and compounds with ACGIH
PPI Samplers off er the convenience of single use to eliminate sampler assembly and
cleaning; small size for worker comfort, even under helmets or other PPE; and a
choice of fl ow rates for maximum fl exibility in pump options, sample duration, and
contaminant concentration. These instructions are for PPI models pre-assembled
with fi lter, support, and impaction substrates.
Preloaded fi lters in some models are available preweighed by SKC for gravimetric
analysis. See the table below.
