OVERVIEW
8
PARTICLE SELECTORS
The
CIP10
equipped with these selectors samples the aerosols according to
the conventional curves described in the European standard NF EN 481
except for the case of very fine particles.
In fact, the
CIP10
’s collection principal generates a discharge of very fine
particles (like the human body). The
CIP 10 R
thereby really does sample the
alveolar deposit.

The selection of respirable alveolar particles is made by impact on a 45 grade
(45 pores per linear inch) polyurethane foam followed by selective filtration by
another foam of the same grade. The fractions of aerosols obtained are in
agreement with the CEN AFNOR 481 and ISO 7708 standards, except for very
fine particles.
