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. 4 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. Ga s Liq uid Sol id S tat e 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. HANNA instruments ® Overview Reference and Combination Electrodes HANNA’s Co mb ina tio n Ref ere n ce reference electrode is used with our half-cell ISE sensors to provide accurate and repeatable measurements. HANNAs combination electrodes incorporate the measuring electrode with the reference making them ideal for field measurements. Reference Electrodes are used to Combination Electrodes include 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. HANNA instruments ® 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.

HANNA instruments ION SELECTIVE MEASUREMENT ® 15 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. Instrument Features • Incremental methods: Known addition Known subtraction Analyte addition Analyte subtraction • Direct methods • pH with Calibration Check™ technology • • • • • Stability indicator Calibration information Single or dual display Colored graphic display Dual channel measurement and logging • Help screens at the touch of a key • Multi-language interface • Manual or automatic temperature compensation • Opto-isolated USB and RS232 outputs • Data logging pH electrode, temp. probe, pH solutions and electrode holder included Large, dot-matrix COLOR LCD w/backlight 16 ION SELECTIVE MEASUREMENT HANNA instruments ® 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.

ION SELECTIVE MEASUREMENT 17 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.

Burette, pH electrode, temp. probe and stirrer assembly included 18 ION SELECTIVE MEASUREMENT HANNA instruments ® 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 SPECIFICATIONS Range Resolution Accuracy Burette Sizes fastest, most versatile titration systems 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 changing the titrant! mV pH Temperature -2000.0 to 2000.0 mV -2.000 to 20.000 pH -5.0 to 105.0°C/23 to 221°F/268.2 to 378.2 K 0.1 mV 0.1/0.01/0.001 pH 0.1°C/0.1°F/0.1K ±0.1 mV (@25°C/77°F) ±0.001 pH (@25°C/77°F) ±0.1°C/±0.2°F/±0.1K (excluding probe error) 5, 10, and 25 mL Burette Resolution 1/40000 Display Resolution 0.001 mL Dosing Accuracy ±0.1% of full burette volume Display Graphic LCD, 320 x 240 pixel LCD Languages English, Italian, Portuguese, Spanish Methods Up to 10,000 methods (standard and user-defined) Burette Auto-Detection Burette size is automatically recognized when inserted into the unit Programmable Stirrer Propeller type, 100-2500 RPM, automatically held within 10% of the set value, resolution 100 rpm Flow Rate User-selectable from 0.1 mL/min to 2 x burette volumes/min pH/mV Measurement Titrators can also perform direct pH and mV measurements Temperature Compensation Manual or automatic (ATC) pH Calibration Manual or automatic at 1-5 points with 4 buffer sets or custom buffers Potentiometric Titrations Acid-Base (pH or mV-Mode), Redox, Precipitation, Complexometric, Non-Aqueous, Ion-Selective, Argentometric (in mV-mode only) HI 901 Titration Methods Fixed mV or pH end-point detection & first equivalency point detection (with the 1st or 2nd derivatives) HI 902 Titration Methods Fixed mV or pH end-point detection & multiple equivalency point detection (with the 1st or 2nd derivatives); back titration Measurement Units User specified expression of concentration units to suit specific calculation requirements mV-Volume or pH-Volume titration curve, 1st derivative curve or 2nd derivative curve, in pH-mode or mV-mode; pH/mV values versus time-datalogging results Real Time & Stored Graphs Data Storage: Up to 100 complete titration and pH/mV logging complete reports Disk Drive: Built-in 3.5" floppy disk drive allows storage and transfer of configurations, preprogrammed methods, custom methods, titration reports and bitmap graph files Peripherals Connections for VGA display, PC-keyboard, parallel printer, RS 232 input, interface for future expansion GLP Conformity Instrumentation data storage and printing capabilities Operating Environment 10 to 40°C (50 to 104°F), up to 95% RH Storage Environment -20 to 70°C (-4 to 158°F), up to 95% RH Power 110V/220 Vac; 50-60Hz Dimensions Width x Depth x Height = 390 x 350 x 380 mm (15.3 x 13.8 x 14.9 in) Weight approx. 10 kg (22 lbs.) with one pump and stirrer assembly ORDERING INFORMATION HI 901-01 (115V) and HI 901-02 (230V) is supplied with (1) 25 mL glass burette, (1) burette driver assembly, power adapter and instructions.
