Gemini VII

Software

The Gemini VII program allows other computer applications to run while an automatic operation is in
progress. The Help menu provides access to the online manual and instructional videos on using the
software.
The Gemini VII program offers a Windows interface with an easy way to collect, organize, archive and
reduce raw data and store sample information files for later use. The reports can be generated to
screen, paper, or exported for use in other applications. Cut and paste graphics, scalable and editable
graphs, and customized reports are easily generated.

User-defined Reports

Report options can be specified when creating the sample information file. When an analysis is run,
data gathered during the analysis process are compiled into the predefined reports. Reports can also be
defined and generated after an analysis has been run. Each selected report is displayed on its own tab
and reflects data collected during the analysis.

Report Features

• After analysis, reports can be viewed, printed, and/or copied and pasted into other documents.
• The report zoom feature provides the viewing of fine graph details and the ability to shift the axes.
• Reports can be customized with a choice of fonts and a logo added to the report header.

Gases

Compressed gases are required for sample analysis with the Gemini analyzer. Gas bottles and a rack
for storage of these bottles should be located near the analyzer. As an alternative, outlets from a central
source may be provided nearby. Gas sources must be able to supply flow rates of 4 liters per minute at
15 psig (103.4 kPa).
Appropriate two-stage regulators which have been leak-checked and specially cleaned are required.
Pressure relief valves should be set to no more than 30 psig. Gas regulators are available from
Micromeritics. Refer to
When helium is used for differential free-space measurement and nitrogen is used as the adsorbate gas,
they should be of the following purity or better:
• Helium - purity of 99.9% (For analysis of materials with very low surface areas, Micromeritics
recommends use of helium with purity of 99.995%.)
• Nitrogen - purity of 99.9% (For analysis of materials with very low surface areas, Micromeritics
recommends use of nitrogen with purity of 99.995%.)
