AirPhoton - Inverse Multi Angle Polarimeter (IMAP) with Polarization - Brochure

The IMAP (Inverse Multi-Angular Polarimeter with Polarization) Nephelometer measures polarized scattered light at multiple angles and at multiple wavelengths. As with our other instruments, we use our feedback flow control system to collect data at multiple size bins ranging from PM1 to PM10. Owing to the small size of the sampling chamber and the overall efficiency of the system, this allows us to determine a full particle size distribution within a span of just 5 minutes.
