The Water & Organic Vapor Sorption Analyzers Vstar is a two station model. The ability to analyze 2 samples simultaneously; manifold temperature control ensures the highest accuracy; independent sample temperature control and wide sample temperature range. • Dosing manifold and vapor source in single • thermostatically controlled chamber • Cold trap to prevent vapors from entering the pump The VSTAR vapor sorption analyzer provide vapor sorption analysis using a wide variety of organic vapors and water at a wide range of temperatures. It measures complete adsorption-desorption isotherms- which is the quantitative uptake of vapor as a function of relative pressure/relative humidity at a user selectable- thermostatically controlled temperature. Specifications: Performance: 2 Station Analysis liquid input: 1 Pressure transducers: 3 Transducer accuracy: <0.05% FS Vacuum pump: Internal Degas type: External Loading samples: Isolation valve for degassing and transferring to analysis station. Quick connect/disconnect of circulating bath and sample cells. Sample cells: Glass of various sizes Analysis temperature range: -20ºC to 100ºC Thermostated manifold: yes (40ºC to 110ºC) P0: Calculated from temperature- measured on empty station- or user entered.
