5. Products Dynamic Vapor Sorption Instruments (DVS)
Our range of DVS instruments measure uptake and loss of moisture and organic vapours by a sample, allowing sorption behaviour to be accurately determined.
Surface Energy Analyser (iGC-SEA)
Our SEA is unique and allows characterizing surface and bulk properties of powders, particulates, fibers, films and semi-solids using a fully automated inverse gas chromatography principle.
Vapor Pressure Analyzer
Our VPA allows determination of the vapor pressure of various ionic liquids and solids under different temperature conditions . This instrument is based on the " Knudsen Efussion Cell" method adopted in the OECD regulations

6. DVS Introduction DVS-Advantage DVS-Intrinsic DVS-Vacuum DVS-ET
The DVS-Advantage is the worlds leading gravimetric technique, using SMS developed technology to facilitate the rapid collection of vapour sorption isotherms on a range of sample sizes with unrivalled sensitivity. Organic vapors and video are standard.
Water sorption analyser specifically designed to meet the needs of small/mid-sized labs. Step-by-step software wizards, help produce high quality data with minimal operator training. The unit’s small footprint makes optimal use of limited bench top space and is expandable for operation of up to 5 units from 1 PC.
DVS-Vacuum
DVS-ET
This dynamic vapour and/or gas sorption analyser can yield real-time sorption kinetics at elevated temperatures as well as work a wide range of sorption molecules at very low partial pressures. In a single chamber, it is possible to perform in-situ outgassing of sample at elevated temperatures and high vacuum which is followed by subsequent sorption experiment
DVS-ET combines the best in microbalance, gas flow and vapour measurement technologies to deliver unsurpassed performance in terms of experimental design as well as instrument accuracy & repeatability. It can achieve experimental temperatures of up to 85°C

7. What can the DVS do for me?
How does my material interact with moisture or solvents and temperature in the vapour phase?
Stability, Performance and Processing issues: Reversible and Irreversible effects of moisture
Create Moisture Isotherms – i.e. Equilibrium moisture content as a function of %RH
Heterogeneity? – Identify the Heterogeneity of a sample batch
Homogeneity? – Identify variance within one sample
Kinetics – Moisture transport properties, how fast or slow?
Energy – How strongly is the moisture bound to the material, surface or bulk?
Identify & Characterise Phase Transition/Changes, e.g. polymorphs, amorphous stoichiometry
Hydration and Solvate Formation
Drying Analysis
Diffusion and Activation Energy
Heat of Sorption
Moisture Uptake/Content? i.e. how much moisture/vapour is taken up or release

8. Surface Energy Analyser
iGC-SEA Introduction
Surface Energy Analyser
Knowledge of surface energetics is important in the formulation design of multi-component systems and the prediction of processing performance.
The surface energy heterogeneity profile constitutes an energy map of the material surface and also allows prediction of product properties, in particular in formulation of blends, composites or coatings.

9. Properties measured by SEA
The SEA provides unique access to the following physico-chemical properties of a wide range of solid materials in a controlled humidity environment:
Dispersive and Polar Surface Energies
Heats and Entropies of Sorption
Acid/Base Interactions
BET Specific Surface Area
Phase Transitions
Sorption Isotherms
Solubility
Competitive (Multicomponent Surface Energy) Sorption
Thermodynamic Work of Cohesion and Adhesion
Surface Energy heterogeneity mapping

10. Application areas where humidity effects can be critical
Pharmaceutical
Stability & shelf life studies, accelerated tests, solubility, Hydrate & solvate formation, packaging, tablet testing, aerosols/inhalers
Pharmaceutical formulation performance can be critically effected by humidity changes leading to Phase changes such as hydration, crystallization and deliquescence of materials
Bio Life and Biomaterials
Understand effects of humidity on skin, hair, Bone, cosmetics, contact lens, agro sprays, hydro-gels
Powders
Spray dry, freeze dry, fluid beds, caking, stickyness, agglomerates
Materials
Textiles, tobacco, paper, paint, construction, timber, polymers, plastics, composites/fiber reinforced laminates, corrosion, ERH Cement, concrete, clay, ceramics, Fibers, Wood, Adhesives, Minerals
Others
Food, Packaging, Rheology, Tribology, Tensilometer, Art Conservation, PCB electronic component testing, Engine testing (aero & auto), Failure mode analysis in Mems, PEM fuel cell, Process, Metrology/Calibration, Climatic, Agro-Chemical, UV curing of print lacquers, WVTR plastic electronics, Reactors
