This kit has been developed in cooperation with Metrohm and includes the IC precol, umn, the reagents for the eluents as well as the buffer and the standard solutions. |
Reversed-phase HELC in eluents of the acetonitrile-formic acid-water system was used in the isocratic modein eluents from 6 to 10 vol. |
The heavy metals are accumulated in the column when eluents based on mineral acids are used. |
The eluents were analysed with a differential refractometer and the peak areas were integrated by a Spectra Physics 4290 integrator. |
