A sample obtained by removing specific fractions by separation or selection techniques
(e.g. heavy liquid, magnetic, sieving, etc.), analysing the fractions separately,
and combining the results mathematically. When not combined, the sample is a
modified sample. This term should not be confused with
composite sample.
