[Assay of vanilmandelic acid (VMA) by gas chromatography using a capillary tube].
The authors describe a method for the determination of urinary VMA as trimethylsilyl derivative by gas-chromatography with a capillary column (OV1 phase). They evaluated the procedure for sensitivity, linearity, analytical recovery and they studied correlation with a spectrophotometric method. The results obtained for normal adults and children are reported. This rapid, sensitive, not expansive method can be adapted for use in a clinical laboratory.
