Part 1 of this two-part module covers the basics of sample preparation focusing on weighing, crushing and grinding, sonication, shaking, dilutions and glassware handling
|Who is it for||
This module is for employees in production quality control and quality assurance who prepare samples for in-process or final testing.
|Why it matters||
Proper sample preparation is critical to ensure that evaluation of batch quality is accurately performed, and to ensure reproducible results. Grinding and crushing, followed by weighing, are the oldest ways of preparing samples for a composite assay of pharmaceutical tablets. Similarly, sonication can be used for degassing, particle size reduction and agitation. Knowledge of these techniques, and their various applications is crucial for quality personnel in pharmaceutical enterprises.
