“Auto Sampler”: Automatic Pretreatment Unit for the “Parshe Analyzer^®” Dynamic Image Analyzer

Abstract

This paper introduces the “Auto Sampler”, an automatic pretreatment equipment designed specifically for the dynamic image analyzer, Parshe Analyzer^®. By simply placing up to 12 powder or slurry samples into designated cups, the system automatically performs a series of processes including dispersant addition, stirring, ultrasonic dispersion, liquid feed, measurement, and cleaning. The implementation of this system significantly improves measurement reproducibility, enhances operational efficiency, and eliminates human error. Furthermore, it supports data integrity compliance, which is increasingly emphasized in the pharmaceutical industry.
