Dynamic Vapour Sorption (DVS)

Dynamic Vapour Sorption explained

Many chemicals including polymers absorb moisture to some extent. The DVS is capable of determining how much moisture can be absorbed by a sample from the air. A delicate balance with two crucibles are placed in a temperature controlled chamber (5 – 85°C) where nitrogen with an adjustable humidity can be lead through. As the sample in one crucible absorbs or desorbs moisture, tiny differences in mass can be monitored and fitted into a plot where the absorbtion and desorption kinetics of a sample are reported in. As this device is capable of measuring more than just polymers we kindly accept other materials, chemicals or substances.
