Quantitative chemical analysis in mixtures requires methods of appreciable selectivity. There is also an ever increasing pressure towards analytical chemists to prove the level of performance of analytical methods by appropriate figures of merit. Selectivity is a property of analytical methods and tools which appears to defy efforts for defining and measuring it. We analyze here a broad spectrum of books, papers, and official documents about selectivity. The approaches and definitions that we have found are quite divergent and sometimes obscure. The greatest dilemma appears to be if selectivity can be meaningfully graded or numerically characterized, i.e., if a figure of merit can be attributed to it. The question is raised if a general definition of analytical selectivity is possible at all.
