https://doi.org/10.1351/goldbook.C01149
A term which characterizes an entire sampling and sample pretreatment procedure, usually represented as a percentage of the original amount of the analyte which is left for measurement (signal formation) after having passed through this procedure. This term also applies to the efficiency of
collection
of an
air pollutant
by an arrestment plant. For particulates, the
collection
efficiency is size related.
