A Karl Fischer titrator, also known as a KF titrator, is used to determine the amount of water in a sample. Because the presence of water can affect many characteristics of a product, including reactivity, stability, and quality, KF titration is important to and is used in many industries. Food, oil, pharmaceutical, and semiconductor industries all use Karl Fischer titrators to maintain the quality of their products. There are two methods that can be used in Karl Fischer titration: volumetry, in which the amount of reagent that has been used determines the amount of water, and coulometry, in which an electrolysis reaction occurs and the amount of electricity used tells us the amount of water in the sample. Volumetry is appropriate to detect water amounts from 1 to 100 milligrams, while coulometry is the better choice for very small amounts of water, from 10 micrograms to 10 milligrams. When choosing the right Karl Fischer titrator, several factors should be considered, including sample size needed, if volumetric or coulometric titration is needed, time the titration will take, and how much of the process is automated and how much needs to be done by hand.

The all-round Karl Fischer Coulometer is the flexible and powerful instrument for fast and precise water determination of samples from any industry with a water content between 1 ppm and 5%.
Features - Color Touchscreen with One Click™ user interface
- User specific Homescreen with Shortcuts for direct access to all Routine tasks
- User interface in English, German, French, Spanish, Italian, Chinese, Russian, Polish and Korean
- Task list for queuing different tasks and direct access
- Generator cell with or without diaphragm available
- Connectivity to LabX titration PC software via USB or direct Ethernet (TCP/IP)
- Common USB printers or the USB-P25 compact paper roll printer for secure and GLP-compliant paper recording
- Coulometric bromine index determination
Reagent Control
The titration cell is always in good condition, as Reagent Control monitors three different parameters and replaces the solvent when necessary in One Click™. The Solvent Manager also empties, fills or replaces the wwwhenever required and keeps the user fully protected.
Automation with Stromboli
Up to 14 samples can be titrated in unattended operation with the Stromboli oven sample changer. Repeatability and efficiency is significantly improved and operation becomes simple, as Stromboli is fully controlled by the titrator. Flexible methods allow multiple blank and sample series with statistics.
User Management
All users have their own Homescreen with Shortcuts for One Click™ start of any task. Routine users can run their Shortcuts to perform routine tasks, but can not accidentally change anything e.g. in the setup. In connection with LabX pro titration PC software the Remote mode offers full support of FDA 21 CFR part 11 regulations.
Flexible powerful methods
Samples that do not release water easily or that cause side reactions can be analyzed using external extraction. Predefined methods that offer direct blank determination of the extracting solvent make this application simple. The method database contains METTLER TOLEDO methods for any kind of coulometric Karl Fischer applications and the method editor makes changes to the methods quite easy.
Bromine Index
One important parameter in quality assurance of petrochemical raw materials and products is the Bromine index. It can easily be determined with utmost accuracy and precision using the elegant coulometric method. The current generator cell and method templates make this application simple and straightforward....

With the possibility to combine up to three different analyses in a single method, the T7 system can be expanded to perform pH and conductivity measurements and titrations. Together with the volumetric The flexible and expandable T7 is designed to fit your needs for a wide variety of applications. With the possibility to combine up to three different analyses in a single method, the T7 system can be expanded to perform pH and conductivity measurements and titrations. Together with the volumetric or coulometric Karl Fischer Kit, the instrument can be used to determine water content down to 1 ppm. Powerful automation options will ensure that you get accurate results with maximised efficiency.
Besides the many advantages of the Titration Excellence line such as One Click® Titration, Plug & Play and the method database, the T7 offers a number of important features:
• Expandable to perform conductivity measurements
• More flexible methods with loops
• Task List for sequential analysis of different methods or series
• Continuous runs
• Automation with Liquid Handler
• Solvent Control for KF solvent monitoring and automatic replacement
• Accompanying pH-stating
• Possibility to upgrade to T9 firmware ... Read More | Intelligent and powerful, the T9 titration system solves complex tasks easily and efficiently. It allows two titrations to run in parallel and independently of one another. The logical condition “if...then” enables the T9 to decide how the analysis should proceed. It can, for Intelligent and powerful, the T9 titration system solves complex tasks easily and efficiently. It allows two titrations to run in parallel and independently of one another. The logical condition “if...then” enables the T9 to decide how the analysis should proceed. It can, for example, first measure the pH and then, on the basis of the result, decide whether acid or base should be dispensed. The T9 additionally allows you to run volumetric and coulometric Karl Fischer analysis simultaneously thanks to the parallel titration feature.
In addition to the many advantages of the Titration Excellence line such as One Click® Titration, Plug & Play, method database and the refinements of the T7, the T9 offers a number of important features:
• Parallel titration
• Conditions within method functions
• Result buffer
• Series Sequence ... Read More | The all-round Karl Fischer titrator is the flexible and powerful instrument for fast and precise water determination of samples from any industry with a water content between 100 ppm and 100%.
