ELPI™ (Electrical Low Pressure Impactor) is an instrument to measure airborne particle size distribution and concentration in real-time. It operates in the size range of 7 nm – 10 µm, and can be applied to various different types of measurements where the requirements for the instrument include wide particle size range and fast response time. Because of its rapid response, the ELPI™ is an ideal measurement instrument for the analysis of unstable concentrations and size distributions, or the evolution of size distributions. Typical applications for the ELPI™ include combustion aerosol and engine exhaust studies, pharmaceutical inhaler development, air quality measurements and general aerosol research.

Dekati's Outdoor ELPI is a modified version of the standard ELPI™ instrument. Like the standard version, the Outdoor Air ELPI™ measures airborne particle size distribution and concentration in real-time. It operates in the size range of 7 nm – 10 µm with the filter stage accessory, and can be applied to various different types of measurements where the requirements for the instrument include a wide particle size range and fast response time. The Outdoor Air version is specially designed for ambient air measurements, although it can be used in other applications as well. The operating principle of the Outdoor Air ELPI™ is the same as that of ELPI™’s where the well-known impactor technology is combined with particle charging and electrical detection. Some features have been added to the Outdoor Air version to make it more suitable for ambient air monitoring:

Features

• Higher sample flow rate (30 lpm) to increase sensitivity
• Integrated humidity and temperature sensor for monitoring the sample
• Option for stand-alone operation

MSP's M1000XP-A Wide-Range Particle Spectrometer (WPS™)M1000XP-B Scanning Mobility Spectrometer (SMS™) Combines laser light scattering, differential mobility analysis, and condensation particle counting to automatically count and size aerosol particles from 10nm to 10,000nm (0.01µm to 10µm) in up to 120 particle-size channels. The Wide-range Particle Spectrometer, or WPS™, represents a new approach to aerosol measurement by combining laser light scattering, differential mobility analysis and condensation particle counting into a single, compact instrument to measure aerosol concentration and size distribution from 10nm to 10,000nm (0.01µm to 10 µm) in diameter.

Simultaneously measures the size and shape of single airborne particles.

The Aspect particle analyser uses Biral’s ASAS technology to simultaneously measure the size and shape of single particles at a high output rate. The ASAS technology uses the complex pattern of the light scattered by particles in a laser beam. Analysis of the spatial pattern of the scattered light gives a measure of the asymmetry of the particle and the integrated intensity a measure of the particle size.
