Register for a variety of on-demand webinars, covering all aspects of Karl Fischer Titration.

Learn to master Karl Fischer Titration REGISTER

Karl Fischer (KF) titration is the method of choice for measuring water content in all types of substances. Although modern KF titration is fast and easy, even experienced users may not be aware of all the factors influencing accuracy and repeatability of results. Join this webinar to learn how to properly prepare your system to work with various samples and avoid common errors.

Learning Objectives of Webinar

How to select the proper KFT method, reagents and standards for your sample.

How to accurately calculate sample size, including burette volume and titer of reagent.
How to avoid common errors during sample preparation & handling.
How to troubleshoot for sample solubility issues, side reactions, ideal pH, stable drift.

Quality Management Of The Karl Fisher System YOU TUBE LINK

Karl Fischer titration is the most widely used method for water determination but requires a known amount of water, a starting point. Administering that water can be a challenge.

Maximising Solubility For Your Sample REGISTER

Accurate Karl Fischer water determination requires the sample to release its water completely. Not all samples will be soluble in the standard media, hence, to address this issue, we will discuss different options to improve the sample solubility.

Find out how co-solvent additions can help improve your titrations.
Does your sample make you boiling mad? We’ll show you how to get even.

Join this Hydranal webinar and bring your Karl Fischer titration closer to perfection.

Tips And Tricks To Analyse Difficult Samples Using The Karl Fischer Oven Technique REGISTER

Karl Fischer (KF) titration is an industry standard method for measuring water content in all types of substances. However, for various reasons some substances are not suitable for a direct Karl Fischer titration:

They release their water only slowly

The water is released at high temperature only
The substances are poorly soluble in KF solvents
They undergo side reactions with KF reagents
They contaminate the titration cell or the electrodes

By using the KF oven technique, the above-mentioned problems can be avoided. This makes the KF oven technique a perfect solution for the analysis of difficult samples.

By viewing this webinar you will learn…

how to analyse difficult samples

how to properly prepare your titration system with KF oven
how to prepare your sample
how to select the optimal heating temperature
which reagents and which water standards you should use to obtain accurate results

After viewing this webinar you will know how to perform accurate titrations using the Karl Fischer oven technique. Additionally, the speakers will reveal tips and tricks to help you in the daily routine. The webinar will finish with live Q&A session.

Do not hesitate and register for this webinar to benefit from the experience of the two speakers.

Achieving Best results In Water Content Determination By Karl Fisher Titration REGISTER

The Karl Fischer titration is the most versatile and generally accepted analytical method for determining water content. It is independent of the sample’s state of matter and is therefore suitable for the analysis of solids, liquids, and gases. Critical to the accurate determination of water content is that the sample is soluble in the solvent mixture, the working pH of the system is not affected by the sample, and side reactions are avoided.

This webinar will provide a brief discussion of the development and principles behind Karl Fischer analysis. An outline of the differences between the volumetric and coulometric approaches to water determination will also be presented. Although each method has its own advantages, the sample will typically dictate the method to be used.

Not only will the sample determine the Karl Fischer approach to take; it also dictates what modifications must be made to the system. To improve solubility, the addition of a co-solvent, the elevation of the system’s temperature and the addition of a homogenizer are all acceptable methods of improving sample solubility. The addition of an appropriate buffer may be required to maintain proper pH control. Problematic functional groups and the specialty reagents that allow for their analysis will be discussed. In addition, the Karl Fischer Oven will be discussed with regard to insoluble or problematic samples.

A brief discussion of how various standards should be used to verify that the system is functioning properly, after modification for the sample, will be covered. Questions are always welcome and will be encouraged throughout the webinar.

Honeywell HYDRANAL™ Composite 5K Reagent for Karl Fischer Titration | Greyhound chromatography Tuesday, May 2, 2023

HYDRANAL™ Composite 5K Reagent for Karl Fischer Titration

Titrating agent for volumetric one-component Karl Fischer titration in aldehydes and ketones (methanol free)

Synonym(s)

DE Solvent; 2-(2-Ethoxyethoxy)ethanol; CARBITOLDE Solvent; 2-(2-Ethoxyethoxy)ethanol; CARBITOL?; Diethylene glycol ethyl ether; Ethyldiglycol; Diethylene glycol ethyl ether; Ethyldiglycol

Honeywell Composite 5K Reagent for Karl Fischer Titration

Specifications

Advantages of Hydranal one-component reagents:

Unlimited water capacity
Convenient and easy to use
The greatest flexibility in working media selection
reduced toxicity compared to methanol based systems
Suitable for methanol-reacting compounds, e.g. ketones and aldehydes
Long shelf life (three years)

Improved Composition

Hydranal-Composite contains all the reactants including iodine, sulfur dioxide, and the bases imidazole and 2-methylimidazole, dissolved in diethylene glycol monoethyl ether (DEGEE). Adding 2-methylimidazole in addition to imidazole improves the stability and eliminates the formation of crystals which can interfere with the titrator’s performance.
