A detailed written description of a laboratory and all
the activities it performs, with emphasis on quality
control and assessment (Chap. 8, pp. 322, 323, 328,
330-332,335,337,338,340).
S. "Chemical analysis".
An attribute of an object that can be distinguished
qualitatively and determined quantitatively. Encompasses the concepts of measurand and analyte
(Chap. 1, pp. 23, 27).
S."Error".
S. "Sample".
A chemical species that is added to a sample or standard in order to form a reaction product with the
analyte(s).
Group reagent. One that separates a small number of
analytes from those present in the sample. Used
within the framework of analytical schemes in Classical Qualitative Analysis (Chap. 5, pp. 217,223, 224).
Identification reagent. One that reacts with an analyte to produce an external effect that can be readily
identified by human senses (e.g. in Classical Qualitative Analysis) (Chap. 5, pp. 219-222).
Masking reagent. One that reacts in solution with
species accompanying the analytes in the sample in
order to cancel their interferences (Chap. 5, pp.
220-222,242).
A material or substance one or more properties of
which are sufficiently uniform and well known for
use in calibrating an instrument or apparatus,
assigning values to materials and systems or assessing analytical methods (Chap. 3, pp. 103, 107, 114,
116,120,122,129,130,134,141,142).

An expression of the standard deviation in relative
terms (as a fraction of unity with respect to the
mean of the set of results) (Chap. 2, pp. 48, 58, 59, 65,
94).
A difference between values of the metrological
scale (e.g. p.-X; X'-X; p.'-X') as defined by different authors (Chap. 2, pp. 45, 50, 83; Fig. 2.5).
