Abstract
Official abstract text for this publication.
A microparticle count apparatus that includes or is connected to a gas reservoir for increasing stability of air pressure at the microparticle counter even when air pressure or air flow rate provided by a nozzle coupled to the microparticle measurement apparatus is unstable.
First claim
Opening claim text (preview).
What is claimed is: 1. A microparticle measurement apparatus, wherein the apparatus comprises: a microparticle counter for counting a number of microparticles in a volume of gas received by the microparticle counter; a vacuum pump for causing the volume of gas to flow through the microparticle counter using negative pressure; and a gas reservoir for increasing stability of air pressure at the microparticle counter even when air pressure or air flow rate provided by a nozzle co…
