Preferred Label : specimen;
Detailed label : specimen in analytical chemistry;
IUPAC definition : A specifically selected portion of a material taken from a dynamic system and assumed
to be representative of the parent material at the time it is taken. Although the
specimen may not be reproducible in time, e.g. it may be taken from a flowing stream
or a portion of blood, no separable sampling error exists since this error is unavoidably
included with the corresponding error of the estimate of the property, function or
analyte being studied. A specimen may be considered as a special type of sample, taken
primarily in time rather than in space. The term 'specimen' has been used both as
a representative unit and as a nonrepresentative (often better than most) unit of
a population, usually in clinical, biological and mineralogical collections. 'Collections'
in this case is used as either a noun or verb. This usage is almost always self-evident,
and thus would not be confused with a time-type sample.;
