Surface Area Analyzer the Micromeritics Gemini VI

Particle and Surface Sciences are pleased to announce that the Micromeritics Gemini VI Surface Area Analyzer boasts improvements that benefit those applications that require extended analysis time and greater stability.

The Gemini was originally designed for use in the carbon black industry, the new Gemini VI boasts improvements to Micromeritics standard Gemini Series Surface Area Analyzers 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 vapor 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 end points, 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.

The Gemini Series of surface area analyzers uses the Static Volumetric Technique to generate high-speed surface area and porosity data.

Product Features :
• Fully automatic operation
• High throughput
• Windows® driven software (optional)
• Choice of analysis mode (scan or equilibrate)
• No pressure overshoot
• Common mode rejection of free space error effects
• No gas flow integrator required
• 21 CFR 11 Software Option
• English, French, German, Italian and Spanish language options
• IQ/OQ Validation service (optional)

Gemini V Models
There are two models in the Gemini V Series, enabling you to get the analyzer that best suits your specific needs. Capabilities are further expanded on each model if the Windows software option is included.

Gemini 2365
The Gemini 2365 determines single-point and multipoint BET and Langmuir surface areas, total pore volume, and micropore analysis by the t-method. Also included is the capability to determine statistical thickness surface area (STSA) of carbon black (refer to ASTM D 6556, ASTM D 3765, ISO/DIS 18852.2, or ISO/CD 4652-2/3).

Gemini 2380
The Gemini 2380 has all the abilities of the Gemini 2365 and additionally can provide BJH pore volume distributions. Up to one thousand isotherm data points may be collected.

Gemini VI 2385C
Originally designed for use in the carbon black industry, the Gemini VI boasts features 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 vapor 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.
