Özet
An HPLC method has been developed for the determination of homocystine. Homocystine was converted to its chromophoric dabsyl derivative and was chromatographed by a reversed phase chromatographic column (mu-Bondapak C) with pH = 3 phosphate buffer-acetonitrile (60:40) as isocratic mobile phase. The derivative was detected by a variable wavelength detector operating at 436 ran. A linear relationship was obtained between peak areas and homocystine concentrations over the range of 0.54-2.68 mu g / 20 mu l.
