Application Note: Identifying Particulate Matter with Hound for Rejected Small Volume Parenterals
30 August 2018

Parenterals, drugs which are injected through the skin or other external tissue, are regulated by the national pharmacopoeias and must be free of any visible particles >50 μm. In this application note, Hound was used to determine the particle identity of contaminants found in small volume parenterals. Hound counts, sizes and identifies particles by automated, imaged directed Raman or Laser-Induced Breakdown spectroscopy paired with spectral reference libraries to quickly identify contaminants.
