There is a new star in the Quantachrome lineup of precision sorption analyzers! The VSTAR™ vapor sorption analyzer goes beyond water sorption to provide vapor sorption analysis using a wide variety of organic vapors at a wide range of temperatures. Meticulous control of the manifold temperature from the vapor source to the sample eliminates the possibility of local condensation of the adsorptive and ensures the most accurate analysis possible.
The VSTAR measures complete adsorption-desorption isotherms, that is the quantitative uptake of vapor as a function of relative pressure / relative humidity at a user selectable, thermostatically controlled temperature. Such measurements are of critical importance to material scientists developing adsorption based technologies for chemical process and environmental applications.
Independent analysis stations, each consisting of: sample cell, isolation valve, pressure transducer, and recirculating dewar. With optional circulating baths, each cell can operate at its own temperature, or with the standard configuration one bath can be shared with all operating cells.
