Measuring and analyzing particles is essential in a variety of applications, including water quality analysis and monitoring, chemical process analysis and monitoring in manufacturing, as well as pure scientific research. This white paper explores the methods for analyzing particles and discusses issues associated with particle analysis.

The ability of an imaging system to resolve details in a particle is essential for accurate measurement. This paper discusses how the optical system and the sensor of an imaging system affect the ability of the instrument to size and characterize sub-visible particles, and what size particles this type of instrument is most effective for.

Imaging particle analyzers can differentiate particles in a heterogeneous mixture and classify them accordingly. The quality of the images captured directly affects the ability of the system to make proper measurements, and therefore affects the ability of the system to differentiate between different particle types. This paper discusses how image quality can affect particle measurement.

Pattern recognition techniques are used in imaging particle analysis to identify and differentiate types of particles in a heterogeneous solution. This paper discusses the theory behind pattern recognition techniques and how these are used in FlowCAM's VisualSpreadsheet for automated particle identification.

In sparse samples, the way an imaging particle analyzer typically calculates particle concentration becomes invalid. The FlowCAM offers a laser-scatter trigger option to overcome this issue. This paper describes how this works, and shows experimental results for low concentration samples.
