Particle Measuring Systems

Company Overview

Particle Measuring Systems' comprehensive line of microcontamination monitors enables users to monitor and qualify contaminants. Specific applications include cleanroom monitoring, parenteral sampling, filter and in-line testing in deionized water and process chemicals, point-of-use monitoring of inert gases, and in-situ particle monitoring. We offer a complete line of testing, training, and consulting services to help meet your contamination monitoring needs. Our expertise is available to find contamination sources, test the cleanliness of parts, characterize processes, or to monitor cleanrooms.

In February 2004, we acquired Molecular Analytics, the leading edge scientific, engineering and production firm with more than 15 years experience in ion mobility spectroscopy.
