Titrators 

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

1. 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.
2. 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.

Titration & Solvent System

• Chemically Resistant Vessel & Tubing
  The glass titration cell and PTFE tubing is designed to withstand the harsh solvents and reagents involved in Karl Fischer titration.
• Sealed Solvent System
  Ground glass joints completely seal the glass titration cell, minimizing exposure to ambient humidity, keeping the system dry, and reducing reagent consumption while saving time between titrations. Solvent may be exchanged in a matter of seconds with a quick fitting adjustment.
• High Efficiency Desiccant
  High efficiency molecular sieve desiccant helps maintain low and stable drift rates within the titration cell while preventing the ingress of ambient humidity into the sealed solvent system.
