Monitoring the stability of fats and
oils
The new Metrohm 743 Rancimat uses the technique of thermal oxidation on fats and edible oils, to determine whether they are new or old
On decomposition of fats and oils, at a specific temperature, the decomposition products are monitored using a conductivity cell and an induction time is automatically calculated which will be standard for a specific oil at the decomposition temperature Comparisons of the measured induction times compared with the standard allows the analyst to determine whether raw material oils are new or old

Measuring the oxidation stability of Biodiesel
The Metrohm 743 Rancimat is a modern, PC-controlled analytical instrument for the comfortable determination of the oxidation stability of Biodiesel (fatty acid methyl esters)
Evaluating the effects of antioxidants in food
The oxidative stability of foodstuffs is of paramount importance in the food industry: the Rancimat provides a simple method to investigate the stability of a new or existing antioxidant/stabiliser
Also this method allows the determination of whether anti-oxidant additives are being effective in preventing oxidation of food materials.
Another application of this analysis is for determining and checking the shelf life of oil/fat finished products.
The new Rancimat has been extensively redesigned to meet the increasing demands of Food Chemists and Regulatory Bodies all over the world.
Some of these improvements in the 743 Rancimat are: 8 measuring positions at two independent temperatures; Individual start times for each sample; Wide temperature range 50-220 C; Inexpensive disposable reaction vessels; Robust Conductivity Cell requiring little maintenance; Comprehensive easy to use software for automatic evaluation of the results; Conversion of Induction times at different temperatures without rerunning the samples, to fulfil the requirements of different international standards; Data storage of all determinations and method parameters, making it easy to compare different batches of oils.
