Metrohm has introduced the 886 Professional Reactor, a rugged and versatile flow-through reactor for fully automatic pre- and post-column derivatisations.
The reactor is said to enable single- or multi-step column derivatisations at any temperature between 25C and 120C.
The system features a variable reactor geometry allowing the adjustment of reactor residence time of the reactants according to derivatisation kinetics.
The reactor facilitates post-column chemistry for any liquid chromatography system.
Methods can be developed and optimised in terms of reagent concentration, flow rates and reactor residence time of the resulting mixture.
Metrohm said the benefits of the 886 Professional Reactor include: broad application range; high derivatisation yields; suitability for complex matrices; derivatisations at high temperatures; and traceability of results due to chip-based intelligence.
The flexibility of the reactor has been demonstrated by optimising four widespread post-column techniques: the relatively slow ninhydrin reaction with amino acids and the fast derivatisations of silicate, bromate and chromate (VI).
