Page 8 of 780 pH Meter / 781 pH/Ion Meter by Metrohm AG

top-of-the-line ion meter easy and comfortable measuring of ion concentrations ­ a metrohm exclusive with the 781 ph/ion meter you can determine the content of different ions using ion-selective electrodes the determinations are either performed by establishing calibration curves or by carrying out standard or sample additions both techniques can be automated with an attached 765 or 776 dosimat for the fully automatic standard addition you need only enter the concentration of your standard and the desired number of additions the rest is taken care of by the ph/ion meter any name can be used for the determined species and the result unit is freely selectable up to 19 standards can be used for calibrations evaluation of the calibration curves or of the additions is carried out automatically by the ph/ion meter you can obtain the following metrosensor ion-selective electrodes from us · with crystal membrane f­ cl­ pb2 cu2 ag s2­ cn­ i­ br­ cd2 scn­ · with polymer membrane na ca2 no3­ k bf4­ · with glass membrane na application know-how included ­ in the internet under www.metrohm.com you will find our application notes as well as the list of all our application bulletins profitable automation whenever larger numbers of samples have to be processed using a sample changer is advantageous for the automated measurement of ph values we recommend to combine the 780 ph meter with our 824 easy sample changer if you also wish to determine ion concentrations for example the fluoride concentration in mouth rinses you can use the 781 ph/ion meter with our 730 sample changer please contact us we will be pleased to advise you about the optimal adaptation of one of our sample changer systems for your application determination of the ion concentration with the 781 ph/ion meter the 765 dosimat performs the fully automatic standard additions while the custom dp40 printer documents the determination 8
