Adsorbate | Optimized for nitrogen in a liquid nitrogen sample bath. Gemini may be used with non-corrosive adsorbate gases having vapor pressures at both room and bath temperatures that are acceptably high relative to the resolution of the 1,000 mmHg pressure transducer. Typically, oxygen, argon, carbon dioxide, butane, methane, and other light hydrocarbons will produce useful data above absolute pressures of a few mmHg. |

P/P0 Resolution | <10-4 |
Relative Pressure Range | 0 to 1.0 P/P0 |
Pressure Resolution | <0.1 mmHg |
Accuracy and Linearity (transducer manufacturer specification) |
Better than ± 0.5% full scale |
Standard Tube |
|
Dewar |
|
An external vacuum source achieving 20 × 10-3 mmHg (or better) at the instrument inlet for oil-based or oil-free pumps. For oil-based pumps, an anti-suckback valve is required to prevent oil from being admitted into the analyzer should there be a power failure. A device to reduce oil vapor backstreaming is also recommended. |
Operating System | 32- bit Windows 7 Professional or higher operating system is recommended for the best user experience. |
Desktop Installation Required | The application should not be installed on a network drive with shared access. Multiple users cannot operate the application at the same time. |
10 Base T or 100 Base T Ethernet Port | If the computer is to be connected to a network, two Ethernet ports are required. If more than one Ethernet based unit is
connected to the same computer, an Ethernet switch will also be required. |
Read/Write Permissions | All users of the application will need Read/Write permission to all directories and subdirectories where the application is
installed. |
Drives | USB port |
Due to continuous improvements, specifications are subject to change without notice.
