A high-performance liquid chromatographic method is described for the determination of hydrogen peroxide in beverages. The method involves the enzymatic conversion of hydrogen peroxide into formaldehyde by catalase-methanol, followed by the derivatization of formaldehyde with 4-amino-3-penten-2-one.
The use of o-phthalaldehyde derivatisation of phenylalanine followed by highperformance liquid chromatography with fluorescence detection as used for amino acid analysis in clinical laboratories was examined to assess its suitability for the monitoring of river pollution by the dairy industry by mea
A method is described for the determination of linear aldehydes (C,-C,) in waters. Aldehydes are extracted into n-pentane after derivatization with 2,4-dinitrophenylhydrazine and quantified by reversed-phase high-performance liquid chromatography with detection at 365 nm. With a 250-ml sample, the l
5-Aminolevulinic acid (ALA), the common precursor of all naturally occurring tetrapyrroles, forms a stable condensation product with 2-amino-3-hydroxynaphthafene which can be identified by its fluorescence. Separation of the compound by reversed-phase high-performance liquid chromatography on RPC-18
