Ion Selective Electrode Analyzer Product Product Description
|
The pH/mV and ion selective electrode analyzer pH/ION 3400i offers the highest degree of flexibility possible. For pH
measurements the ion selective electrode analyzer can be calibrated manually or automatically and offers simultaneous display of pH
and temperature. For measurements with ion-selective electrodes the pH/lON 3400i ion selective electrode analyzer offers
concentration display in mg/l. The ion selective electrode analyzer also displays directly in mV to ±999.9 mV in 0.1 mV steps;
and to ±1999 mV in 1 mV steps.
Of course, even in these higher ranges the ion selective electrode analyzer calculates the concentration from a mV resolution of 0.1
mV. Calibration of the ion selective electrode analyzer is carried out with up to three standards (selected from 16 standards
in the range of 0.01 to 1000 mg/l).
Operating on either line power or rechargeable battery for up to 1500 hours with "LoBat" warning means that the ion selective
electrode analyzer can be used in the laboratory or in the field. Lightweight and compact, the rugged ion selective electrode
analyzers are IP 66 (hose proof) and IP 67 (submersible). The ion selective electrode analyzer has a built-in datalogger for
up to 500 measurements together with GLP calibration protocol offers a comprehensive documentation of the results. The ion
selective electrode analyzer supports analog or digital data transfer (RS 232), automatic recognition of stable measurements
(AutoRead), electrode evaluation and calibration interval monitoring functions to ensure reproducible and reliable measurements.
What is a Ion Selective Electrode Analyzer for?
Ion-selective measurement is a method for determining the concentration of dissolved ions. Potassium ions, sodium ions,
fluoride or chloride are examples of such cations and anions which are directly measured in solutions. Indirect methods such
as titration allow the determination of aluminum, nickel ions, or sulfate. Measurement with ISE's, like the measurement of pH,
is a potentiometric method.
ISE's are in two configurations:
1. separate ion-selective electrode and reference electrode
2. combined ion-selective electrode with built-in reference electrode
The ion-selective membrane of the electrode consists of a sparingly soluble salt of the ion to be measured (solid state electrodes),
a PVC-membrane, modified by an ion exchanger or ion carrier (matrix electrodes), glass (glass electrode) or a gas-permeable plastic
(gas-sensitive electrodes). The activity of the ions to be measured determines the electrode current. With increasing
activity of the anions the voltage turns more negative, with increasing activity of cations, more positive. An ion selective
electrode analyzer uses the electrode signal to calculate the concentration of the sample. The wide range of possible
applications includes, for example, the measurement of fluoride concentration according to DIN 38 405. Chloride content
determination in concrete samples or nitrate concentration determination in fruit juices are further examples of the ways in which
ion-selective measurement technology can be applied. An introduction to ion-selective measurement technology as well as
application reports are available on our CD-ROM entitled "Principles of measurement technology".
