TY - JOUR T1 - A Comparison of the HIAC Particle Size Analyzer, an Automated Image Analyzer and the PMA Membrane Microscopic Method of Particle Size Analysis JF - PDA Journal of Pharmaceutical Science and Technology JO - PDA J Pharm Sci Technol SP - 58 LP - 60 VL - 40 IS - 2 AU - Joseph R.

This paper compares the results from a HIAC particle size analyzer, an automated image analyzer and the Pharmaceutical Manufacturers Association (PMA) membrane microscopic method. Ten lots of a dry powder antibiotic were used for the analysis. No correlation is readily evident among the different methods of particle size analysis. The HIAC results are generally lower than the PMA membrane microscopic method and those of the automated image analyzer. ER -
