The Gemini VII series analyzers provide single and multipoint surface area and pore size
measurements. Three models are available — the Gemini 2390a, 2390p, and 2390t.
The Gemini 2390a and 2390p are enclosed in the same size cabinet. The only physical difference
is the P
0
(saturation pressure) tube, which is installed on the Gemini 2390p, allowing continuous
measurement of the saturation pressure.
The Gemini 2390t is in a slightly larger cabinet allowing the use of a larger dewar and longer
sample tubes for extended analyses. This model also is equipped with a P
0
tube.
Most application features are available on all three models, with the exception of a continuous P
0
measurement and a few reports.
The instrument is intended to be operated by trained personnel familiar with the
proper operation of the equipment recommended by the manufacturer as well as
relevant hazards involved and prevention methods. All use, other than that described
in this manual, is seen as unintended use and can cause a safety hazard.
The instrument is intended to be used as per applicable local and national regulations.
