title: Automated urinary steroid profiles by capillary column gas-liquid chromatography and a computing integrator.
abstract: 13 Urinary steroid metabolites have been determined by automated gas-liquid chromatography with a 20-m glass capillary column and a computing integrator. Concentrations up to 2 mg/24 h computed by the integrator compare well with those obtained by peak height measurements. At higher concentrations discrepancies occurred, paticularly for the C21 steroids where falsely low values were calculated using peak heights. Mean excretion by healthy males and females of seven steroid metabolities is presented.
