Automated Thermometric Titration to Determine TAN and TBN in Oils and Lubricants

OEL CHECK GmbH is growing fast and has a throughput of about 200’000 samples per year. They guarantee a 28-hour service to their customers, which are manufacturers of turbines, engines, blow molders, paper machines, hydraulic excavators, to name but a few. OEL CHECK GmbH does not only provide fast results but – more importantly – practical advice and expertise based on the interpretation of these results.

As their customers expect fast solutions, OEL CHECK GmbH depends on the fastest and most efficient technology in their labs. For TAN and TBN analysis they use automated thermometric titration. Thermometric titration has several advantages compared to potentiometric titration. It is much faster and more robust. A typical thermometric titration takes just about two minutes. Moreover, electrodes do not need to be regenerated between determinations. By thermometric titration we can increase our sample throughput theefold. At the same time, much less manual work is required, says Paul Weismann, managing director of OEL CHECK GmbH. Thermometric titration is implemented in tiamo™, making control and operation of the system perfectly easy.
