Speed of Sound DVS: Moisture, Organic Vapor, and Co-Adsorption in Material Processing and Separation Science Surface Measurement Systems' new Dynamic Vapor Sorption (DVS) instruments utilize the patent-pending Speed-of-Sound sensor. Measuring moisture, organic vapor, and co-adsorption isotherms, this unique DVS technology opens new areas of sorption characterization for material processing and separation science. Representative sorption kinetic data [...]
Speed of Sound Dynamic Vapor Sorption (DVS) - "The only method to directly measure solvent concentrations." Surface Measurement Systems introduced new DVS products last year. These instruments extend the capabilities of our Dynamic Vapor Sorption family of instruments by introducing a revolutionary new sensor. The speed of sound sensor increases the reliability and accuracy of [...]
November 14, 2016 DVS and iGC Applications on pharmaceuticals, fibers, fillers, polymers, biomaterials and minerals The workshop will cover in-depth Dynamic Vapor Sorption (DVS) technique and iGC-SEA (Inverse Gas Chromatography - Surface Energy Analyzer), the most-advanced scientific instrument in determining surface energy. Individual whose works are in line with studying materials such as straws, bricks, polymers, [...]
13 June 2016 | Back to Newsroom Surface Measurement Systems announced the launch of Dynamic Vapor Sorption instrument – DVS Adventure. DVS Adventure is a water vapor sorption analyzer measuring sorption and desorption isotherms over a broad range of humidities and temperatures. It offers unprecedented temperature stability and humidity performance. It provides valuable information about [...]
07 May 2015 | 08:59 By Jan Gorgol Cellulose is the main component of cell walls from plants, making it the most abundant organic polymer on Earth! Cellulosic biomass forms supramolecular structures comprising cellulose crystals as well as disordered, water-accessible fractions. Recently, Carlos Driemeier and co-workers from the Brazilian Bioethanol Science and Technology [...]
30 April 2015 | 09:00 By Jan Gorgol The photovoltaic effect is the creation of a voltage in a material upon exposure to sunlight; it is how a solar cell converts sunlight into electricity. It was first observed by Becquerel in 1839. However it was not until the advent of Silicon technology’s in the 1950’s [...]
08 April 2015 | 09:00 By Dr Jeremy Wingate | Rotronic Instruments (UK) Ltd. Tablet coating in general Pharmaceutical tablet coating involves the application of a coating composition to a moving bed of tablets with the use of heated air to facilitate the evaporation of the solvent. Several different types of coating are [...]
23 February 2015 | 11:32 By Jan Gorgol Cont. Humidity Effects on Structure in Regenerative Tissue Engineering Tissue engineering is growing as an area of research which aims to regenerate damaged tissues such as perforated eardrum membranes. This is achieved through the use of biomaterials which provide cells with the necessary biological triggers [...]
23 February 2015 | 11:32 By Jan Gorgol Humidity has huge effects on fiber and particle adhesion and micro-manipulating them in a broad variety of areas. Just a few of the areas where researchers have looked at such effects include manipulation of wood fibers , micro encapsulation of perfumes and drugs, effects of [...]
