Effects of Sample Concentration on Theoretical Plate Number (SI-35 4D)


Effects of Sample Concentration on Theoretical Plate Number (SI-35 4D)

Please use this column with suppressor type ion chromatography system.

When analyzing sulfate and chloride ions using IC SI-35 4D,
an anion analysis column, the theoretical plate numbers show a tendency to decrease with increasing concentrations of 10 mg/L or more.

Sample : 20?L each
Cl
