Optical particle counters use the principle of light scattering to detect particles above a certain size. These instruments are typically employed by environmental engineers to measure particulate ...
In order to quantify the count and size of subvisible particles in eye care products, the USP <789> test is carried out. This consists of utilizing a light obscuration particle counter and counting ...
Measurement of cloud drop size distributions with the Knollenberg model FSSP-100 light-scattering counter can lead to artificial bumps or knees in the distributions at ∼0.6 μm and sometimes 2–4 μm ...
