This article provides practical guidance on using automated particle image analysis to detect agglomerates in pharmaceutical formulations. Particle agglomeration has the potential to compromise clinical efficacy and must therefore be closely monitored and controlled during manufacture. Experimental data illustrate different strategies for the detection of agglomerates on the basis of size, shape and, where necessary, chemical identification.
Compared with manual microscopy, automated imaging is fast, statistically reliable and cost efficient, making it a valuable tool for product development, process troubleshooting and QC.
