Overview
ISE Electrode Types
ion selective electrodes can be grouped into three general categories based upon construction.
Solid State Electrodes are
available as both single half-cells or as
combination electrodes complete with
reference electrode. These electrodes
incorporate a solid sensing surface made
of compressed silver halides, or solid
crystalline material. HANNA’s offering
includes sensors for the determination of
bromide, cadmium, chloride, cupric,
cyanide, fluoride, lead and silver ions.
Solid body construction is rugged for
long life.
Theory: A solid state electrode develops
a voltage due to ion-exchange occurring
between the sample and the inorganic
membrane. An equilibrium mechanism
occurs due to the very limited solubility
of the membrane material in the sample.

ION SELECTIVE MEASUREMENT
Liquid Membrane
Electrodes are available as single
half-cells or as combination electrodes
complete with reference electrode. The
sensing surfaces of these electrodes are
comprised of a homogeneous polymer
matrix containing organic ion-exchangers
selective for the determined ion. These
sensors incorporate easily replaceable
membrane modules and are available
for measurements of nitrate, potassium
and calcium.
Theory: The potassium electrode was
one of the earliest liquid membrane
sensors developed of this type. The
membrane is usually in the form of a
thin disc of PVC impregnated with the
antibiotic valinomycin. The exchanger,
also known an ionophore, is a ring
structure that fits potassium ions inside
like a lock and key. This type of
membrane is not as rugged as the solid
state type so they are designed for easy
replacement of the sensing module.

HANNA’s
Gas Sensors are combination
electrodes that detect dissolved gases
in a solution. No external reference is
required for these electrodes. The sensing
element is separated from the sample
solution by a gas permeable membrane.
HANNA’s offering includes the HI 4101
Ammonia electrode and the HI 4105
Carbon Dioxide electrode.
Theory: A gas sensor works due to
the partial pressure of the measured gas
in solution. The dissolved gas in the
sample diffuses into the membrane and
changes the pH in a thin film of unbuffered
electrolyte on the surface of the internal
pH sensor. Diffusion continues until the
partial pressure of the sample and the
thin film is the same. The pH change
is proportional to the dissolved gas in
the sample.

accurate and repeatable measurements. HANNAs combination electrodes incorporate the

provide a stable voltage and electrolytic
contact to permit a voltage gradient to be
measured across a measurement membrane
such as an ISE. HANNA has designed an easy
to use, unbreakable plastic, double junction,
quick fill, sleeve style reference electrode with
a cone style junction to work with the ion
selective electrode family of sensors. The
design forms the liquid junction with the test
solution at the tip of the junction cone and
not further up the cone surface. The design
produces a highly stable reference electrode
with reasonable low flow rates. The model
HI 5315 is a silver/silver chloride electrode
half-cell with a permanent gel filled internal
cell. The outer fill solution is easily replaceable
and serves as a buffer zone between the
internal chloride ion containing gel and the
sample solution. HANNA offers a complete line
of silver-free fill solutions to optimize your ion
measurement. A fast responding liquid
junction, excellent reproducibility, and ease
of use will mark this reference as your “best”
in the lab.
a sensor and reference electrode in a single
electrode body. Our combination ion selective
electrodes provide the same selectivity and
response as our ISE half-cells, but include our
superior double junction reference into the
same electrode body. Combination solid state
electrodes have a built in solid state sensor and
quick refillable reference electrode. Our liquid
membrane and fluoride combination electrodes
have replaceable module construction and the
HANNA double junction reference stability.

Three Methods of Analysis
Potentiometric ion analyses with ISEs are performed by use of one of three
methods, each entailing its own advantages: Direct Potentiometry, Incremental
Methods, and Potentiometric Titration. HANNA offers a solution for each of
these methods, for more details please refer to pages 14-19.

Measurement: Direct Potentiometry
HI 98184 • HI 98185 Portable ISE Meters
Direct Potentiometry is a widely used method
of performing ion analysis with ISEs. This method is highly
effective when the user must quickly measure large batches of
samples at many concentrations. Our direct reading meters
such as the HI 98184 and HI 98185 display concentration of the
unknown sample by a direct reading after calibrating the
instrument with 2 or more standards. Ionic strength
adjustments are made to both samples and standards. In
some applications quick and reliable measurements can be
made on-site without taking samples back to the laboratory.

Measurement: Incremental Methods
HI 4222 pH/ISE Bench Meter with Special ISE Features for Ease of Use
Incremental Methods are useful techniques used
to determine ion concentration quickly in samples whose constituents are variable or concentrated. Incremental methods
have some inherent advantages over direct potentiometry. The
techniques can reduce errors from variables such as temperature, viscosity, pH or ionic strength. The electrodes remain
immersed throughout the process thus reducing sample carry
over and possible liquid junction changes in the reference and
analysis steps are reduced. Known Addition, Known Subtraction,
Analyte Addition, and Analyte Subtraction methods are four of
these incremental techniques. All techniques involve adding a
standard to the sample, or sample to the standard and the
meter calculates the sample’s ion concentration directly.

Measurement: Incremental Methods
First Step
The first step in performing an
incremental method analysis is to enter
the required parameters including sample,
ISA and standard volumes and standard
concentration.
When repeating the analysis on another
sample, the parameters do not need to
be reentered.
Sequence of Readings
Once the variables are entered, the
user is guided step-by-step through
the measurement.
Results
The results are automatically
calculated and shown together with
all the parameters used.
Help Screen
Users can consult the on-screen help
from any mode simply by pressing the
HELP key.
The initial mV measurement is made
before the addition, next is the addition,
and then the second measurement
is made.
At this time, results can be saved into a
log file. If necessary, the user can edit the
parameters without having to redo the
entire analysis.
The instrument will then display the
meaning and options available of the
current screen.

Measurement: Potentiometric Titrations
HI 901 • HI 902 Automatic Titrators
a Potentiometric Titration can increase the
precision of ISE measurements and also the number of ionic
species that can be determined. ISEs are commonly used as
indicators for the titrant or sample species to follow the
progress of a precipitation or complexation titration. A small
change in reactant addition corresponds to a large change in
electrode potential at the stoichiometric end point. An
example of a precipitation titration is the determination of
chloride using silver nitrate. A Silver ISE can be used to follow
this titration. A complexometric titration is used for the
determination of calcium. A calcium solution is titrated with
the complexing reagent EDTA. During the titration there is a
gradual decrease in the free Ca+2 ion concentration as more
EDTA is added. The end point corresponds to the point when
all the Ca+2 is complexed. The progress of this titration can be
monitored using a calcium ISE.

Measurement: Potentiometric Titrations
With Clip-Lock™, it only takes a couple seconds to exchange the reagent burettes to
perform a different titration.
With conventional titrators, there is the
risk of cross contamination of titrants
when exchanging reagents.
Reconfiguring the titrator for different
sample methods also consumes time
and reagents. Each method may need
different reagents and care must be used
when purging and cleaning the burette.
To avoid these problems, HANNA provides
the Clip-Lock™ exchangeable burette
system to prevent cross contamination
while reducing loss of time and reagents.
Having several prepared burettes on
hand will make the HANNA 900 series the

available. Interrupting an important cycle
of analysis due to a malfunctioning
burette is a thing of the past. With the
HANNA Clip-Lock™ system you can simply substitute the burette and complete
all your tests with the same titrant!
HANNA’s
burettes feature a threaded
screw connection to prevent leakage
problems. Burettes are available in 5 mL,
10 mL & 25 mL sizes and are made of
chemically resistant material to ensure
many years of trouble-free operation.
Keep extra HANNA 900 series burettes on
hand for quick substitutions without
