FLOW INJECTION NONAQUEOUS SOLVENT NEUTRALIZATION TITRATION PROCESS AND APPARATUS

摘要

A flow injection nonaqueous solvent neutralization titration process and system is provided. The predetermined quantity of a known titrant is used to derived calibration values based on different predetermined concentrations of a desired component in a sample. The quantity of the titrant agent in excess of an amount necessary to completely react with the sample is added and then subsequently the amount of the unreactant titrant agent is determined. From this value, the calibration values that have been stored, for example, in a look-up table can be used to determine the actual concentrations of the desired component in the sample. Alternatively, the sample can be mixed in a fluid carrier solution having a predetermined quantity of the titrant agent and then the resulting by-products of the reaction with the sample and the titrant can be inserted into a pH buffer solution so that the excess titrant will change the concentration ratio of the acids to bases and by measuring this change and comparing with the calibration values, the unknown concentration of the desired component in the sample can be discovered.
