Quantachrome’s Youtube channel now includes a video demonstrating how easy it is to obtain water-vapour sorption data on two samples simultaneously using its fully automated Aquadyne DVS analyser.

Water-vapour sorption is a slow process controlled by diffusion kinetics, so determining water sorption isotherms is often considered a tedious task.

By analysing two samples simultaneously, however, the Aquadyne effectively doubles sample throughput, lending an important advantage for those industries that would do more water-vapour sorption measurements for characterising materials and products, such as pharmaceuticals, food, ceramics, building materials, paper and so on, were it not for the usual poor sample throughput.

The Aquadyne is a benchtop unit with a self-regulated, precision temperature and relative-humidity controlled sample chamber that easily accommodates two samples, each hanging from its own high-resolution microbalance.

The chamber door offers good accessibility to both sample positions called ‘hangdowns’, doubles as a convenient staging shelf for sample pans and includes a heated window for fog-free visibility.

Since there is no external circulator bath and no large environmental chamber required to house the unit, setting up analyses of two samples has been simplified.

This video demonstrates the superior ergonomics of the Aquadyne DVS and the quality of data users can expect from this dual-sample DVS analyser.
