A rapid gas chromatographic method for the quantitation of volatile fatty acids in urine. Propionic acid excretion in vitamin B12 deficiency


, : A rapid gas chromatographic method for the quantitation of volatile fatty acids in urine. Propionic acid excretion in vitamin B12 deficiency. Journal of Chromatography 81(1): 65-69

Five volatile fatty acids, C2 to C5, were separated by gas chromatography on a column of 25% neopentyl glycol adipate and 2% phosphoric acid on chromosorb W AW-DMCS. Urine was first extracted with ether then ethyl acetate to remove interfering neutral substances. Patients with pernicious anaemia excreted propionic acid which is not present in normal urine.
