Title: micro- technique Long Title: IUPAC Gold Book - micro- technique DOI: 10.1351/goldbook.12298 Status: current Definition Prefix used to denote that the technique measures small quantities, either with respect to the amount of sample studied, or with respect to the change in the properties measured. Notes 1) This prefix has been applied to many thermal methods, and the equipment associated with them, for example, microbalance, microreactor, microcalorimeter and also to the technique itself: microthermal, microscopic, and the property studied: microstructural. 2) The opposite prefix, macro-, is also occasionally used. 3) Mathematically, micro = \(\upmu\) = \(\pu{E-6}\).
