Because solid food takes more time to digest and to break down the protein and send it to the muscles, it can be best to take a protein shake immediately following a workout, since protein shakes only take about 30 minutes to reach the muscle after ingestion.
selectivity. (analytical chemistry). The ability of a type of method or instrumentation to respond to a specified substance or constituent and not to others. (electronics). The ability of a radio receiver to separate a desired signal frequency from other signal frequencies, some of which may differ only slightly from the desired value.
Selectivity in analytical chemistry. (IUPAC Recommendations 2001) Abstract: The correct use of the term âselectivityâ and its clear distinction from the. term âspecificityâ are discussed. A definition of selectivity is given, and it is rec-. ommended that the use of this term be promoted and that the use of the term. âspecificityâ be discouraged. 1. INTRODUCTION. A very important quality criterion of an analytical method is its capability to deliver signals that are free.
