Intrinsic
Water DVS
The development of Dynamic Vapour Sorption (DVS) by Professor Darryl Williams revolutionized vapour
sorption measurements in 1994. The manual desiccator test was brought into
the modern world of isotherms and computerized data capture and walk away
operation. All SMS models are designed, developed and produced in house.
The latest DVS models include a new, purpose designed SMS Ultra-Balance,
replacing dated Cahn technology.
The neat Intrinsic system shown right is the ideal instrument for routine use
in a QC lab or busy company.
Within R & D, applications range from studying polymorphism and stability to
studies of the bulk and surface adsorption effects of water and organic
vapors. It’s also a QC analysis technique for both scale-up and production,
and can be found measuring the efficacy and permeability of packaging materials, and the effects of
humidity and temperature on the samples within the packaging.

Advantage
Water & solvent DVS
The DVS Advantage is the most advanced and versatile dynamic
gravimetric vapour sorption capabilities in the SMS range;
indeed it is the most complete system on the market.
Applications in food, pharmaceuticals, fibres, films and porous
materials are supported with extensive applications experience,
and include simple stability testing using water isotherms up to
sophisticated prediction of solid-solid interactions.
Sample pre-heating.
Organic vapours facilities
Active control of relative humidity and organic
vapour.
Flexible sample geometry.
