Principles of Identification

  • Boris L. MilmanEmail author


In this initial chapter, concepts and terms related to qualitative chemical analysis are outlined and discussed. Chemical identification is defined as assigning an analyte to one from known chemical compounds or a group/class of compounds. General principles for identification through the use of chemical tests and instrumental measurements are formulated. Qualitative analytical procedures and approaches to implement them are classified. Components of identification procedures are further described. Objects for identification such as compounds, substances, and analyzed samples are discussed in great detail, including identifiers of the objects. Known chemical substances, which amount to more than 110 million entities, are statistically reviewed. Finally, two key metrological issues, traceability in identification operations and qualitative scale of measurements, are discussed.
