Estimation of size resolved losses (penetration efficiency) of any parts of the sampling line.

The measurement set-up allows for:

• monodisperse testing aerosol (20-400 nm, salt solutions - usually ammonium sulphate, etc.),

• penetration estimation up to 99.99999%,

• built-in correction for the detector (CPC) inconsistency,

• automated and fully controlled measurement process.

PACC is a new unit of CAIS-ECAC, but the hosting laboratory at ICPF CAS has a long lasting history in these measurements including testing of filtration efficiency of over 250 different types of PPE (Personal Protective Equipment) during COVID pandemic.
