Column:
— size: l =0.25m, Ф=4.6mm,
— stationary phase: styrene-divinylbenzene copolymer R (8 μm) with a pore size of 100 nm,
— temperature: 55°C
Post-column solution: a carbonate-free sodium hydroxide solution diluted 1 to 25, previously degassed, which is added pulse-less to the column effluent using a 375 μl polymeric mixing coil.
Detection: pulsed amperometric detector or equivalent with a gold indicator electrode, a silver-silver chloride reference electrode, and a stainless steel auxiliary electrode which is the cell body, held at respectively + 0.05 V detection, + 0.75 V oxidation and 0.15 V reduction potentials, with pulse durations according to the instrument used.
