QVA - Model M020 - Aerosol Generator - Brochure

When using a particle counter for filter integrity testing, challenges in excess of six million particles (≥0.3μm)* per cubic foot of air (2.1x108 per cubic meter) are required. Traditional Laskin nozzle and thermal aerosol generators are designed for use with photometers which require more than10 μg/l of an aerosol challenge for leak testing. Concentrations of 10 μg/l are on the order of 100X greater than what is optimal for leak testing/sizing with a particle counter.
