title: [Quantitative determination of aromatic carboxylic acids with glass-capillary-columns (author's transl)].
abstract: With a glass-capillary column 20 aromatic acids, probably present in urine, were analysed quantitatively. In comparison with a packed column the capillary column offers several advantages: a higher resolution; a greatly reduced analysis time, an increased sensitivity. Though a split system is used, repeatability and linearity are suitable for quantitative analysis. The advantages are best recognized by the analysis of urine specimens of patients with a metabolic disorder (phenylketonuria).
