Annex I
Trace analysis. An analytical process specially suited
to the identification or quantitation of analytes
present in proportions below 0.01 % (100 ppm) in
the sample (Chap. 1, pp. 33, 35, Fig. 1.24).
Ultramicro analysis. A type of chemical analysis
where the initial size of the sample aliquot subjected
to the CMP is less than 1 mg (Chap.1,pp.32; Fig.1.23).
S. ''Analytical process".
The science of (bio}chemical measurements (Chap.
3,pp.106,109,112,115,141,142).
S. "Standard".
A multidisciplinary entity that aims to expand and
enhance analytical chemical information by using
less material, time and human resources (with the
aid of computers).
An analytical system that performs column chromatographic processes (gas or liquid chromatography)
and possesses an on-line detector for continuous
monitoring of the fluid that emerges from the
separation column. Because it provides analytical
information, a chromatograph is an instrument
(Chap. 4, pp. 145, 148, 149, 151, 163-165, 167, 170,
171,186,187,195).
S. "Separation".
A word that describes a broad range of a highly
efficient analytical separation techniques based on
multiple mass transfer between a mobile phase and
a stationary phase (Chap. 4, pp.168, 188, 190).
Gas chromatography. A chromatographic technique
where the mobile phase is a gas (into which the
sample aliquot is inserted) and the stationary phase
is a solid or a liquid supported on an inert solid that
is placed in a column (Box 2.16).
Liquid chromatography. A chromatographic technique where the mobile phase is a liquid (into which
the sample aliquot is inserted) and the stationary
phase is a solid or a liquid that is either supported on
an inert solid which is placed in a column or spread
onto a thin layer of a support (in Thin Layer
Chromatography) (Box 2.16).
S. "Chemical analysis".
The process by which interferents in a sample are
removed using a separation technique to indirectly
enhance selectivity (ChapA, pp. 165, 194; Fig. 4.15.2).
