Metrohm has brought out the 871 Advanced Bioscan, which analyses four different phenols, in different matrices, using ion chromatography (IC).
This method determines the quantities of phenol, cresol, dimethylphenol and trimethylphenol in less than 16 minutes.
The separation of the four phenols is performed using a potassium nitrate/sulfuric acid/methanol mobile phase with a C18 separation column with Pulsed Amperometric Detection (PAD) using a glassy carbon electrode.
By applying three different working potentials in sequence, the working electrode is cleaned and regenerated after measurement, preventing fouling.
The 871 Advanced Bioscan is maintenance free.
It contains a PAD cell with built-in injector and column heater.
Instrument control is via the IC Net software.
The Bioscan can be used with a standalone pump to form a standalone PAD detection system or can be integrated into a standard IC setup (for example 850 Professional IC or Advanced Modular IC) meaning the instrument is capable of analysing anions and cations.
The Magic Net Software can also be used for manipulation of the results (IC Net is used only to start-up the hardware).
Magic Net runs samples and calibrates standards.
All the chromatographic raw data goes into the Magic Net database where the determinations can be reported or exported manually or automatically into an external package.
Shutdown of the IC hardware can also be performed directly from Magic Net.
Magic Net provides: definable control cards for monitoring chromatographic parameters (retention times, resolution, theoretical plates and so on) over time; improved integration algorithm and manipulation of calibrations and standards (bracketing, check standards, blank subtraction); monitoring of the lifetime of IC consumables (such as filters, guard column, piston seals and so on) to prevent instrument down time; options for manipulation of results from the database; reprocess, overlay multiple determinations for reporting; and reconfiguration of running the instrument to one button IC for novice operation.
