Summary It has been shown that a variety of mixtures and multivitamin preparations may be analysed for their Vitamin C (ascorbic acid) content using cathode ray reverse sweep polarography. Preliminary results indicate that the method, as described, is flexible and has the apparent advantages of minimal sample preparation involving no separation, large tolerance towards suspended matter and coloured materials, extensive freedom from interference, rapidity and considerable sensitivity. Some difficulties (and their solutions) associated with the use of this method are outlined. Given further refinement the method seems to have considerable potential as a practical analytical technique.
