Fraction Counting Analysis
Statistics for characteristics of particles present in a sample can be calculated directly by computing the fraction of particles in various identified categories. These categories are usually defined in consultation with the client and can include empty versus full, smooth versus uneven, spherical versus elongated, amorphous, and so on.
Particles are identified and grouped by a senior trained analyst until the required number of particles has been counted. The fraction of each particle type relative to the total are presented in a report. Information obtained from these analyses include statistics on sample morphology, shape characterization and encapsulation efficiency.
