Abstract:
Formamide with low conductivity and a neutral or slightly basic pH is provided. Such formamide may be used in a sample loading solution for capillary electrophoretic separation of biomolecular analytes to enhance the efficiency of sample injection into the capillary and the intensity of the signal. Formamide of the present invention may be obtained by first purifying the formamide to a conductivity of below 7 micro mho, and then adjusting the pH of the purified formamide with a base to a range of about pH 6. 5 to 7. 5. The purification may be carried out by first removing the water from the formamide, and then distilling the dried formamide until the conductivity of formamide is below about 7 micro mho.
