Definition
material entity that is the specified output of a material sampling process
Semi-Formal Definition:
every instance of ‘material sample’ is exactly an instance of ‘material entity’ that ‘is specified output of’ some ‘material sampling process’
Examples
- a 10 mL portion of bioreactor culture collected during mid-log phase for cell-viability analysis; a portion of harvested supernatant contained in a labeled vial and taken from a chromatography pool for impurity testing; a powder portion taken from the middle of an API drum for composition-uniformity testing; a tablet selected from a production batch during compression for hardness testing
