A generic designation applied to a body or individual requiring chemical information with a view
to solving a social or economic problem.
Relative standard deviation, expressed as a percentage (Chap. 2, pp.48, 58, 82).
S. "Method".
S. "Sample".
An expression of a relative quantitative result: the
amount of analyte in a given volume or mass of
sample (Chap. 6, pp. 248, 250, 252, 254 - 256, 259, 260,
262-269,271-278,280,281).
Cut-off concentration. The concentration chosen by
the analyst in establishing a given probability level that
the binary response will be correct (Chap. 5, pp. 206,
207,211,212,240).
Threshold concentration or limiting concentration.
Highest or lowest level, established by the client or
legislation, to be used in deciding whether a sample
or object warrants assignation of a given attribute
(Chap. 5, pp. 206-208, 240).
S. "Sample".
S. "Concentration".
The body of mathematical calculations leading to
the expression of the analytical result from tabulated
data (chemical standards, constants, conversion
factors) and test data produced by a CMP applied to
the sample and standards (Chap. 4, pp. 144, 161, 171;
Fig. 4.17).
To have an instrument produce a signal and transduce it into a readily measured physical quantity (a
primary datum). Third step in the information
hierarchy of Fig. 1.15 (Chap. 1, pp. 23, 28).
The action of detecting (Chap. 1, p. 21, 23, 28). The
process of measuring for qualitative purposes
(Chap. 5, pp. 202, 204, 205, 207-211, 213, 220, 230,
234,236,240; Box 5.1).
S."Error".
The process by which the amount or concentration
of an analyte (or analyte family) in a sample is
established. The central level in the hierarchy of
Fig.U8 (Chap. 1, pp. 5, 16,21,24,26,28,31-35).
The difference between an individual result in a set
and the mean of the set (random error) (Chap. 2,
pp.47, 48,50,57 -59,63,65,67,81,82,93,94,99).
A part of an apparatus, instrument or analyser that
can serve one or more of a wide variety of functions.
