Metrohm has developed a simple method for the analysis of four phenols in a variety of matrices using ion chromatography.
Provided the sample can be solved into the mobile phase, the quantities of phenol, cresol, dimethylphenol and trimethylphenol can be determined in less than 16min.
The separation of the four phenols is performed using a potassium nitrate/sulfuric acid/methanol mobile phase with a C18 separation column.
The detection method is pulsed amperometric detection 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 Metrohm flow cell is completely maintenance free.
