Trace Element Speciation for Environment, Food and Health
For the analysis of mercury and methylmercury, the use of sodium tetra-
phenylborate as derivatisation reagent has been reported.72,73 Due to the fact
that sodium tetraphenylborate is a very mild derivatisation reagent, it can only be
used for ...
L. Ebdon, Royal Society of Chemistry (Great Britain), 2001

Handbook of Solid Phase Microextraction
The derivatisation agent can bring an additional source of interferences and
errors into the system and the derivatisation process should be carried out only
when necessary. Derivatisation is more often used in SPMEÀGC applications,
due to ...

Hyphenated Techniques in Speciation Analysis
The most common derivatisation procedures rely on ethylation with sodium
tetraethylborate (NaBEt4) which is water soluble and fairly stable in aqueous
media.24 Attempts at multielement and multispecies derivatisation using NaBEt4
have ...
Joanna Szpunar, Ryszard Lobinski, 2003

Applications of Solid Phase Microextraction
Derivatisation of these groups into less polar analogues prior to SPME will thus
increase the coating/water partition coefficient, improve the SPME efficiency and
improve method sensitivity. Few papers have, however, been published on the ...

Residue Analysis in Food: Principles and Applications
7.8 DERIVATISATION 7.8.1 Principle and Effects of Derivatisation 7.8.1.1
Principle Most of the analytical methods involving gas chromatography use
derivatisation before analyte detection. The main objective of derivative formation
is to allow ...

Applications of HPLC in Biochemistry
If the concentration of the compounds of interest is insufficient to allow detection
the sample may require derivatisation. 10.7. Derivatisation Derivatisation can be
carried out before or after chromatography (Lawrence and Frei, 1976). 10. 7.1.
