  • Title: Comparison of capillary electrophoretic and liquid chromatographic determination of hypoxanthine and xanthine for the diagnosis of xanthinuria.
    Author: Bory C, Chantin C, Boulieu R.
    Journal: J Chromatogr A; 1996 Apr 12; 730(1-2):329-31. PubMed ID: 8680593.
    Abstract:
    A capillary electrophoretic (CE) method for the determination of hypoxanthine and xanthine in urine was developed to diagnose xanthinuria. The linearity was excellent up to 200 mumol l-1 for the two compounds and the limit of quantitation was 2 mumol l-1. A comparison o the results obtained using CE was made with those obtained by the high-performance liquid chromatographic (HPLC) technique described previously. With regard to specificity, sensitivity and reproducibility, the results are similar but CE is more rapid than HPLC.
