SKC Diesel Particulate Matter Cassettes are
designed for sampling in atmospheres where
it is necessary to separate DPM from other
respirable dust (such as coal dust). Single-use
SKC DPM Cassettes are tamper-evident sealed
to ensure sample integrity. Each streamlined
p l a s t i c c a s s e t t e c o m p r i s e s a n i m p a c t o r
with precision sapphire orifice, impaction
substrate, and two heat-treated quartz filters.
The impactor screens out respirable particles
≥ 1.0 μm. Particles less than 1.0 μm are collected
on the filter. Samples are analyzed for organic
and elemental carbon content using a highly
sensitive Evolved Gas Analysis (EGA) technique
with thermal-optical analyzer as specified in
NIOSH 5040.

Sampling Equipment
The SKC DPM Cassett e is designed for use with an appropriate sample pump and cyclone
that pre-selects non-respirable particles*. An SKC Universal XR, AirChek
® 2000, or AirChek
XR5000 sample pump can provide the specifi ed fl ow rate. Use the SKC Cassett e/Cyclone
Holder (Cat. No. 225-1) to secure the cassett e when used with the GS-1 Cyclone.
* A cyclone is not necessary in all sampling situations. It should be used in sett ings where larger particulate is likely to clog
the impactor.
