Acoustic-Resonance Spectrometry as a Process Analytical Technology for Rapid and Accurate Tablet Identification
Joseph Medendorp

The US FDA frequently orders recalls of tablets because of labeling problems, e.g., the wrong tablet appears in a bottle. A rapid, nondestructive method of online analysis and label comparison before shipping could obviate the need for recall or disposal of a batch of mislabeled drugs, thus saving a company considerable expense. ARS is accurate and precise as well as inexpensive and nondestructive, and the sensor is constructed from readily available parts, suggesting utility as a PAT.
