AirPhoton - Model PI Neph -Polar Imaging Nephelometer
The PI Neph (Polar Imaging Nephelometer) is a high grade laboratory instrument designed for an in-depth understating of particulate properties. It provides a full particle characterization including the size distribution and the complex refractive index from hyperangle scattering measurements. Amongst its capabilities, the PI-Neph includes: measuring light scattering from 3° to 176°, angular resolution of less than 1°, standard configuration of 2 wavelengths but customizable for 1-3 wavelengths, polarization and a GRASP™ included software package.
GRASP software included package contributes to the retrieval of parameters such as size distribution, percent sphericity or complex refractive index. In addition, it can provide an overview of the multi-source retrieval capabilities of the algorithm and suggest exploring further analysis. The fact that the PI Nephelometer brings so much capabilities also makes it more complex to use. In this regard, the learning curve to get to most of his capabilities are accompanied with an extensive instruments training. In sum, the instrument will not only provide a deeper understanding on particulate matter but also will introduce trainees to GRASP software capabilities.
