A measuring system that produces analytical information (primary data) which can be related to
the presence or concentration of analyte( s} in the
sample. The realization of the analytical technique
and the second level in the hierarchy of Fig. 1.17. A
wide variety of instruments exist that are classified
in Fig. 4.16 (Chap. 1, pp. 3,4,6,10,11,13,14,19,21,
23-27,30,31,34,35; Chap. 4, pp. 145, 147 -149,151,
153,161,163-166,168-175,179,180,194,195,199,
200).
S. "Chemical analysis".
Chemical or physical perturbations of various types
that systematically alter one or more steps of a CMP
and hence the analytical result in terms of selectivity
(Chap. 2, pp. 69-71,80,81,89,96; Fig. 2.13).
Series of CMPs carried out by different laboratories
under the supervision of a competent body to analyse aliquots of the same sample with a view to determining the same analytes. Used to check the results
produced (and their uncertainties) for a variety of
purposes (Chap. 8, p. 331, 332, 340, 342).
A process by which dissolved ionic species are
separated using an active solid called an "ionexchange resin" (Chap. 4, pp.152).

S. "Solid-liquid extraction".
The range of values about the mean where a result
can be assumed to lie with a given probability when
a CMP is applied to aliquots of the same sample
(Chap. 2, p. 64).
The analyte concentration providing an analytical
signal that can be statistically distinguished from an
analytical blank (Chap. 2, pp. 205, 207 - 211, 240).
The analyte concentration that gives a signal taken
to be the lower limit of the linear range of the calibration curve (Chap. 2, pp. 46, 67, 68, 98).

The linear portion of the calibration curve where the
sensitivity (slope) remains constant (Chap. 2, pp.
67-69,88).

Analytes the proportions of which in the sample
exceed 1 % of their masses (Chap. 1, p. 33; Fig. 1.24).
