Gold and Silver for the New 871 Advanced Bioscan from Metrohm
11 June 2007
The new 871 Advanced Bioscan expands Metrohm's modular ion chromatography system by including carbohydrate analysis in the range of IC applications.
The 871 Advanced Bioscan is a pulsed amperometric detector equipped with an injection valve and a column oven.
The measuring cell of the 871 Advanced Bioscan and the insulated column oven form a single unit that is optimally protected against environmental influences.
The three-electrode measuring principle is applied; a gold working electrode is used as standard. Measuring cells with silver, platinum or glassy carbon working electrodes are available.
MODULAR CONCEPT FOR MAXIMUM FLEXIBILITY
The modular concept of the Metrohm IC system allows perfect adaptation of the setup to the particular application. The 871 Advanced Bioscan can be used as a stand-alone system, but can also easily be incorporated in an existing system for the determination of anions and cations.
A VERSATILE DETECTOR
Apart from carbohydrates, the 871 Advanced Bioscan can also be used to determine alcohols, sugar alcohols, sugar acids, polysaccharides and other oxidizable or reducible substances.
The newly developed Metrosep Carb 1 separation column is particularly suitable for the determination of carbohydrates using alkaline eluents and pulsed amperometric detection. It is very stable under alkaline conditions and yields outstanding separations of mono- and disaccharides. It is also suitable for the analysis of sugar alcohols and oligosaccharides.
