The acids were fully protonated by passing the aqueous samples through BioRad AG 50W-X8 (H+) resin and dried thoroughly before refluxing with 3-benzyl-1-p-tolyltriazene in acetone. The benzyl esters that formed partitioned quantitatively into cyclohexane and were determined by gas-liquid chromatography with a flame-photometric detector (phosphorus mode) and a glass column (5% OV-210 on 80/100 mesh Gas Chrom 0). Linear recovery curves were obtained. Inorganic orthophosphate did not interfere with urine analysis, although it could be easily removed by Ca(OH)2 precipitation.</dcterms:abstract> <dc:format>application/pdf</dc:format> <dcterms:issued>1979</dcterms:issued> <dcterms:bibliographicCitation>First publ. in: Analytical Chemistry ; 51 (1979), 12. - S. 1949-1953</dcterms:bibliographicCitation> </rdf:Description> </rdf:RDF>
