Preferred Label : unit;
Detailed label : unit (item/portion/individual) in analytical chemistry;
IUPAC definition : Each of the discrete, identifiable portions of material suitable for removal from
a population as a sample or as a portion of a sample, and which can be individually
considered, examined or tested, or combined. In the case of sampling bulk materials
(or large packages), the units are increments, created by a sampling device. In the
case of packaged materials, the unit may vary with the level of commercial distribution.
For example, an individual piece of candy is the sampling unit at the consumer level;
a package of individual pieces is the sampling unit at the retail level; a carton
of packages is the sampling unit at the wholesale level; a pallet of cartons is the
shipping unit at the distribution centre level; and a truckload of pallets is the
consignment unit at the manufacture level. Before packaging, the bin containing the
individual pieces would be the bulk lot (or batch) for sampling.;
