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”.
