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 ...

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 ...

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 ...
