How to assess detergent etching performance in one hour

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.

How Nouryon ranks detergent performance when the traditional tools fail

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.

Assess the cleaning efficiency as a function of detergent concentration within an hour

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.

How to rank detergent performance in less than 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.

What is dissipation?

Talking about QCM-based instrumentation, one often comes across the concepts of ‘dissipation’ or ‘damping’. Here we explain what these concepts mean, and why are they relevant.

How to measure swelling of thin films with QCM-D

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.

How to characterize viscoelastic properties with QCM-D

Wood, ice and the disks in a human spine are all viscoelastic materials. Viscoelasticity is a quality involving both viscous and elastic properties at the same time. QCM-D is a surface sensitive technology that can characterize the viscoelastic properties of thin films.

What can QCM-D technology be used for?

Surfaces are all around us. To control the macroscale we need to understand and tune the nanoscale. To our aid, we use analytical tools, such as QCM-D
