Coulometric Karl Fischer Titrator Capabilities
Dynamic Titrant Dosing
The dynamic titration speed allows for timely and accurate titration results by relating the amount of iodine generated to the mV response from the Karl Fischer reaction. This provides for a larger generation of iodine near the beginning of a titration and more precise pulses near the titration endpoint.
Drift Rate Compensation
The HI904 Coulometric Karl Fischer Titrator automatically adjusts the titration calculation to account for the effects of any ambient humidity entering the titration cell. This provides a more accurate result by correcting for water not present in the actual sample.
Selectable Endpoint Criteria
The HI904 employs a dual platinum pin electrode for bivoltammetric endpoint determination. Users may choose termination criteria based on mV stability times or drift rates.
Multistage Cell Preparation
A pre-titration stage eliminates residual water present in the solvent and the cell, providing a reliable baseline start to analysis. Standby mode then keeps the solvent dry between titrations and when the titrator is not in use.
Coulometric Titration System
Fritted (Diaphragm) Genertor
Fritless (No Diaphram) Generator
Purposeful Generator Design
Two styles of generators are available for the HI904 Coulometric Karl Fischer Titrator; a fritted design ideal for samples with low water content and high accuracy demand; and a fritless generator allowing for easier cleaning and maintenance.
Precision Iodine Generation
Our dosing algorithm allows for an extremely small amount of iodine necessary for the Karl Fischer reaction to be generated electrolytically using a pulsed current up to 400 mA, delivering iodine accurately and precisely.
Chemically Resistant Vessel & Tubing
Sealed Solvent System
High Efficiency Desiccant
