In this section you'll find a selection of valuable learning materials relating to the use and application of titration techniques, including technical articles, applications, webinars and eSeminars.
The presence of excessive water in plastics adversely affects the performance of polymeric goods which is why water determination is of crucial importance. This article describes the accurate and straightforward determination of the water content using the Karl Fischer Oven Method in ten different plastic types that are not amenable to direct Karl Fischer titration.
For the production of milk and dairy products, the water content plays an important role, technologically as well as economically. Therefore, national and international laws and agreements protect and regulate the definition of products and the production processes in dairy technology. Determining the water content in milk and milk products can be easily achieved with Karl Fischer (KF) titration.
Titration Solutions #8: Conductometric Titration: Practical Solutions for Locating the Equivalence Point
It was in 1930 when I. M. Kolthoff wrote his review article “Conductometric Titrations” in which he highlighted the need for implementing conductometry in more applications than was the case at that time. Offering advantages to analytical chemists compared with other titrimetric procedures, conductometry is currently widely used in many applications including, but not limited to, pharmaceutical analysis.
This application note describes the determination of the acid number and free fatty acids in olive oil.
This application note describes the automated determination of the peroxide value using the DIS-Cover technique.
This application note describes the determination of the saponification value according to DIN EN ISO 3657.
In a thermometric titration, reagent solution (titrant) is added to the sample at a constant rate until the endpoint is reached. The changing temperature of the reaction solution is plotted versus the volume of titrant added. This brochure from Metrohm presents some practical applications of thermometric titration.
In order to use the result of a chemical analysis for other purposes, its quality must be assessed. One important quality feature is the probability that the result coincides with the ‘true’ value. It is obtained by the evaluation of the measurement uncertainty. The webinar ‘Evaluation of Measurement Uncertainty in Titration’ guides you through the individual steps of this evaluation by using the comprehensive example of the titrimetric content determination of sodium hydroxide with potassium hydrogen phthalate. The shown principle can be applied to any other titrimetric analysis.
Ms Annette Buschmann and Dr Andreas Lemmer from the State Institute of Agricultural Engineering and Bioenergy at Hohenheim University, Stuttgart, Germany provide an application report on biogas analysis describing how the VOA (volatile organic acid)/TIC (total inorganic carbon) value, which is an essential tool for assessing the fermentation process, can be determined inexpensively using a simple titration method and the right laboratory equipment.
Sigma-Aldrich offers a brochure describing high-quality titration reagents for volumetric titration. Topics include titration reagents and solutions, packaging options, dilution of concentrates and indicators.
