The traditional way of assessing etching properties can be time-consuming. But there are faster ways. Here we present a method that will help you assess the etching effects in one single wash cycle and in less than an hour.
When, Nouryon (former AkzoNobel speciality chemicals), launched a new surfactant with a good dermatological profile, they wanted to prove superior performance vs competitive benchmarks. As the current test methods were not sensitive enough, they turned to an analysis using QSense cleaning profile.
What is the optimal surfactant concentration to use in a cleaning formulation? Here we show how the cleaning efficiency as a function of detergent concentration can be assessed within an hour.
Throughout the cleaning product life cycle, ranking of performance is an important type of assessment. It can be quite time-consuming, but with the right approach, it is possible to evaluate and rank the product performance in less than one hour. Here we tell you how.
The ability to take up and release water is central for many materials, such as hydrogels, whose function depend on the ability to hydrate and dehydrate. Hydration and swelling are also central when dealing with hygroscopic materials. QCM-D can be used to characterize such swelling phenomenon.
