USP Chapter <788>

Of the United States Pharmacopeia devoted to practices and methods used to measure particle size and concentration in injectable liquids. This chapter aims to evaluate and determine the amount of particle contamination in parenteral products. The two primary methods for analysis are light obscuration and the microscope particle count test.
