In the present study we report new data on the reaction of three representative thiols--captopril (CAP), cysteine (CYS) and N-acetylcysteine (NAC)--with two commercially available propiolate esters--methyl-propiolate (MP) and butyl-propiolate (BP)--under flow conditions. The reactions were investigated on-line using sequential injection analysis (SI) and(More)
In this work we report a sequential-injection (SI) analysis method for the direct determination of phosphate in urine with on-line dilution and photometric detection. The developed SI manifold incorporated an additional dilution coil (DC) connected to one of the ports of the selection valve. On-line dilution was performed by aspirating a zone of sample with(More)
