Water vapor sorption analyzer / digital / benchtop

DVS Advantage Elevated Temperature 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 and repeatability. It can achieve experimental temperatures of up to 85°C, extending the experimental capabilities when compared to the DVS Advantage.

DVS Advantage ET uses a dry carrier gas, usually nitrogen, and the user can select one of any two vapor sources. Precise control of the ratio of saturated and dry carrier gas flows is enabled with mass flow control combined with the use of unique real time vapor concentration monitoring for both water and organics. A known concentration of the selected vapor then flows over a sample suspended from a recording ultra-microbalance, which measures the weight change caused by sorption or desorption of the vapor molecule. It is these dynamic flow conditions that enable the sorption/desorption process to be so rapidly studied.

Key benefits include:

Single finger access for fast sample loading
High performance digital microbalance
Pre-heating of the sample up to 150ºC
Full digital control of sample pre-heater and analysis temperatures
Multiple vapor reservoirs for rapid change from water to organic solutes
Large water vapor reservior
Unique in-line transducer technology for measuring real time organic or water vapor concentrations
Near Infra-Red (NIR) and Raman fibre optic ready instruments
