✦ Synopsis

An automated contmuous tltratlon method IS described m whuzh the use of a piston burette as a vanable-volume mJectlon devxe In a flow system allows a contmuous-flow tltratlon of a sample solution to be performed slmdarly to classical batch tltrlmetrlc procedures It IS found that by plottmg the peak herght for each mjectlon versus the tltrant volume Injected, a tltratlon curve very slmdar to a batch tltrlmetric cmve can be obtamed, and an eqmvalence volume can be precisely determmed A hnear relatIonshIp between the logarithm of the equwalence volume and the logarithm of the carrier concentration has been observed over a wide concentration range The use of reagent IS kept to a mmlmum because tltratlons are performed by addmg only mlcrohtres of reagent The time required for the tltratlon IS comparable to the time consumed by a process tltratlon system
