Definition

Noun: 1. A type of chemical analysis: The act or process of identifying the elements or compounds present in a substance, without necessarily determining their precise quantities. The focus is on the "what" is present, not "how much." 2. A non-numerical assessment: More broadly, any examination or evaluation that classifies and describes the characteristics, properties, or components of something, rather than measuring its numerical magnitude.
