    Abstract:
    Open-tubular glass capillary columns have been used in gas chromatography in combination with mass spectrometry (GC-MS) and computer methods to study human diseases. Patients with maple syrup urine disease excrete not only alpha-keto and alpha-hydroxy acids but also six other metabolites which hitherto have been overlooked. The GC-MS methods demonstrated that a group of patients suffering from hereditary progressive loss of hearing have an impaired metabolism of leucine, leading to the accumulation of 3-hydroxyisovaleric acid and 3-methylcrotonylglycine. GC using the capillary columns proved suitable for mapping of the carbohydrate profile of human seminal fluid and for the analyses of organic compounds accumulating in human adipose tissue. The high resolving power and long life of the glass capillary columns suggest that they will be valuable in the diagnosis and study of human disorders.
