Assessing hydrolytic rancidity by monitoring the acid number
Base and acid numbers are crucial for classifying fats and oils as well as fat- and oil-containing products. The ongoing hydrolytic rancidity of oils and fats is a result of the water-induced cleavage of triglyceride ester bonds. Thereby, fatty acids are released; simultaneously the acid number increases.
The compact 855 Robotic TAN/TBN Analyzer is ideally suited to take over the nonaqueous TAN titration. On one hand it saves you a lot of valuable time and increases your data reproducibility, on the other hand you avoid contact with organic solvents and aggressive titrants. Last but not least, only an automated system guarantees that the electrode is always treated in the same way, which is very important if a certain conditioning procedure is required between the single measurements. Whatever your conditioning procedure is, it can easily be adapted to the Robotic Analyzer.
