Ion Selective Electrodes Catalog

Product catalog summary

Introduction
HANNA Instruments has launched a new series of Ion Selective Electrodes (ISEs) tailored for industries such as research, agriculture, and water quality monitoring. These electrodes are complemented by ionic strength adjusters, filling solutions, and certified standards to ensure high performance and durability.

ISE Electrode Types

Gas Sensors: Utilize a gas permeable membrane to detect dissolved gases like ammonia and carbon dioxide.
Liquid Membrane Electrodes: Employ a polymer matrix with ion-exchangers for ions such as nitrate and potassium.
Solid State Electrodes: Constructed from compressed silver halides or crystalline material for ions like bromide and fluoride.

Reference and Combination Electrodes
Reference electrodes provide stable voltage for ISEs, while combination electrodes integrate the sensor and reference electrode, making them ideal for field measurements.

ISE Electrodes Overview
The document details specifications for various electrodes, including measurement range, pH range, temperature range, and potential applications for ions such as ammonia, bromide, cadmium, calcium, and more.

Measurement Methods

Direct Potentiometry: Directly measures ion concentration.
Incremental Methods: Involves adding known quantities of ions.
Potentiometric Titration: Uses titrants to determine ion concentration.

Solutions and Accessories
Includes ISE standards, gas sensor fill solutions, ionic strength adjusters, and silver-free reference fill solutions. Accessories such as replacement caps and membrane kits are also available.

Reference Chart
A comprehensive chart provides details on electrode types, filling solutions, and standards for various ions.

Specifications
The document lists a wide range of ISE standards and solutions, detailing concentrations and volumes, typically in 500 mL bottles. It also describes ionic strength adjusters and electrolyte solutions for consistent ionic strength and improved measurement accuracy.

Procedures
Outlines the use of direct potentiometry and incremental methods for ion analysis, highlighting their efficiency and error reduction capabilities. Step-by-step guidance is provided for performing these measurements, including calibration procedures.

Instruments
Describes HANNA Instruments products like the HI 98184 and HI 98185 portable ISE meters, and the HI 4222 pH/ISE bench meter, featuring waterproof protection, multiple calibration points, data logging, and USB connectivity.

Recommendations
Emphasizes the importance of using correct filling solutions and ISAs for optimal ISE performance, and recommends regular calibration and maintenance of electrodes and instruments.

Accessories
Lists various accessories, including replacement parts, membrane kits, and conditioning solutions, designed to enhance the functionality and longevity of HANNA Instruments' ISE products.

Key Features

Key Features of Clip-Lock™ System

Allows quick exchange of reagent burettes.
Burette sizes available in 5 mL, 10 mL, and 25 mL, made of chemically resistant material.
Potentiometric titrations range from -2000.0 to 2000.0 mV, -2.000 to 20.000 pH, and -5.0 to 105.0°C.
High accuracy and resolution for measurements.
Graphic LCD display, real-time and stored graphs, and data storage for up to 100 complete reports.
Connectivity options include VGA display, PC-keyboard, parallel printer, and RS 232 input.

Specifications of Clip-Lock™ System

Burette Auto-Detection: Automatically recognizes burette size.
Programmable Stirrer: Propeller type with adjustable RPM.
Flow Rate: User-selectable from 0.1 mL/min to 2 x burette volumes/min.
pH Calibration: Manual or automatic at 1-5 points with various buffer sets.
Titration Methods: Includes acid-base, redox, precipitation, complexometric, non-aqueous, ion-selective, and argentometric titrations.

Ordering Information
Lists different models (HI 901 and HI 902) with specific voltage options, each supplied with a 25 mL glass burette, burette driver assembly, power adapter, and instructions.

Company Information
HANNA Instruments emphasizes its commitment to providing a complete range of analytical products with solid build quality, customer service, and competitive pricing since 1978.

HANNA s ion selective electrodes can be grouped into three general categories based upon construction. > Solid State Liquid Gas Theory: The potassium electrode wasone of the earliest liquid membrane sensors developed of this type. The membrane is usually in the form of a thin disc of PVC impregnatedwith theantibiotic 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. > areavailable as both single...
