Improvements to standard Gemini surface area analysers directly benefit not only carbon black producers and users, but also applications that require extended analysis time and greater stability
Originally designed for use in the carbon black industry, the new Gemini VI boasts improvements to Micromeritics standard Gemini series surface area analysers that directly benefit not only carbon black producers and users, but also applications that require extended analysis time and greater stability.
A larger cabinet allows for longer sample tubes and a larger Dewar.
The larger Dewar provides a very stable thermal environment in which to measure the isotherm resulting in improved repeatability from one sample to the next.
The capability to monitor continuously the saturation vapour pressure (P0) of the adsorptive using a dedicated P0 tube and transducer has also been added.
This feature allows the instrument software to accommodate, at each data point, any minute change in the saturation vapor pressure that may occur during the course of the analysis.
The result is a more meticulously determined relative pressure.
These improvements combined with features such as automatically generated or user-defined pressure tables with user-selected endpoints, free-space determination and correction options, and a variety of reports make the Gemini VI a valuable tool for the determination of surface area and pore size distribution.
