ABSTRACT: A problem in chemical analysis in connection with measurements of a substance normally
occurring in a sample, or identification of a substance which should not exist
in a sample, is insufficient selectivity. In this article, we analyze this problem and propose remedies. We use
a real doping case to illustrate how
chemical noise causes a serious selectivity problem, probably causing a
false positive outcome.
