Reinventing volumetric Karl Fischer titration: OMNIS KF!

KF Titrando

No matter whether your samples contain just trace concentrations of water or whether they are mostly water, the Titrando family of Karl Fischer titrators has got you covered.

These coulometric and volumetric titrators can be customized to your requirements and offer a wealth of options to make your work easier and safer: optional software control, sample preparation and automation solutions, and many more.

KF Titrando with Touch Control and operator

Key features

  • Accurate determination of any water content (0.001 to 100%)
  • Operation with tiamo software for full compliance
  • Coulometers with automatic start of titration and reagent exchange
  • Volumeters with intelligent dosing elements

KF Titrando systems (14)

Automated volumetric KF titration including sample preparation

MATi 11
Fully automated system for volumetric Karl Fischer water content determination in up to 53 samples. This system is controlled with tiamo™ and consists of an 815 Robotic USB Sample Processor XL, a 901 Titrando, a Polytron PT 1300 D and extensive accessories.The samples are weighed out into beakers, sealed to protect against humidity and placed on the rack. Before the actual titration, a defined volume of KF reagent is added and the sample is pulverized with the help of a Polytron. The water that is released is titrated afterwards. Even samples of poor solubility, e.g., tablets, can be analyzed without difficulty with this method. The use of solubility promoters can be avoided in this way.

Automated volumetric KF titrations

MATi 10
Fully automated system for volumetric Karl Fischer water content determination in up to 24 samples. The system is controlled with tiamo™ and consists of an 814 USB Sample Processor, a 901 Titrando and extensive accessories.The samples are weighed out into the beakers, sealed to protect against humidity and placed on the rack. Before the actual titration, they are dissolved in a defined volume of KF working medium, after which the water content is titrated.This method is particularly suitable for samples that dissolve readily in the KF working medium. In addition, solubility can be improved by using suitable solubility promoters.

Automated coulometric KF titrations

MATi 04
MATi 4 is a fully automated system for coulometric KF titrations with high sample throughput. Up to 160 samples in 6 mL vials can be placed on the sample rack of the Sample Processor. The sample is pipetted into an external coulometric cell and then titrated there. The system is controlled with the tiamo™ titration software.

851 Titrando with generator electrode without diaphragm

2.851.0110
Coulometer including generator electrode without diaphragm.Coulometry is the ideal method for water determination in liquids, solids and gases when it comes to water determination in the trace range (10 µg to 10 mg absolute water). In addition, coulometry is an absolute method and thus no titer determination is necessary.Coulometric titrations are carried out easily and quickly with the 851 Titrando.Recommended measuring range: 10 µg - 200 mg absolute water

High-end titrators for any water content and any requirements

Titrando is Metrohm’s instrument family for exacting demands.

Like the potentiometric Titrandos, the Karl Fischer versions offer excellent measuring accuracy and a host of features that will meet any requirements.

The KF Titrando family of titrators includes a variety of coulometric, volumetric, and combined titrators, enabling you to analyze any water content from 0.001 to 100%.

KF Titrando: the way you want it

KF Titrandos can be fully tailored to your specific requirements.

They can either be used as stand-alone titrators or integrated into an overarching network. Operation has been optimized for both scenarios: you can use a convenient Touch Control unit or the elaborate tiamo software to tap the full potential of your Titrando system.

KF Titrando coulometers: safe and convenient

If you perform coulometric titrations with a KF Titrando, you will benefit from increased convenience and improved safety.

These titrators recognize the addition of sample automatically and start the titration. Moreover, you have the option to automate reagent exchange with a Titrando coulometer and Dosinos or Dosing Units. You therefore don’t have to open the cell and direct contact with the toxic reagents is avoided.

KF Titrando volumeters: clever and convenient

Titrando volumetric titrators can be used in conjunction with intelligent Exchange or Dosing Units.

These devices have a data chip with the relevant data on it. In this way, you can benefit from increased convenience and security, because you don’t have to enter this data yourself and errors are minimized.
