WebThe Centrifugal Particle Mass Analyzer (CPMA) allows direct classification of aerosol by mass-to-charge ratio, with an unrivalled transfer function. The CPMA uses opposing electrical and centrifugal fields to classify particles, with the ability to vary the electrical field and rotation speed to select different particle masses. WebThe CPMA is a fundamental standard for particle mass — provided particles are singly charged, the mass setpoint depends on just the set speed and voltage, and the physical …
