3-methoxy-4-hydroxymandelic acid (vma) by microfiber chromatography.
A method is presented for the rapid, precise, quantitative measurement of 3-methoxy4-hydroxymandelic acid (VMA) in urine. The method is unique in that it utilizes silica-gel-impregnated glass fiber as a support medium for thin-layer chromatography.

[1962) Clin. Chim. Acta 7, 285-291), a one dimensional paper chromatographic method with diazotized p-nitroaniline staining and the commer...
متن کاملDetermination of urinary 3-methoxy-4-hydroxymandelic acid (vanillylmandelic acid) by paper electrophoresis.
