Diacell® iGM Controller
Intelligent pneumatic pressure controller and indicator for gas membrane DACs
- The Diacell® iGM Controller employs fully digital control technology to provide stability and high slew rate when varying the gas pressure in the gas membrane of DACs;
- It enables the selecting gas pressure targets, min and max pressure limits, specific pressure variation slew rates as well as more complex pressure profiles;
- The Diacell® iGM Controller is particularly suited to experiments where the gas pressure needs to be controlled actively over long periods of time or where accuracy and reproductibility are critical;
- The unit comes with RS232, IEEE, Ethernet, USB ports and front panel digital touch screen as standard;
- Option: low temperature gas membrane cells in addition require the GM Controler Relief Valve Option for safe operation;
- High Pressure Manager (HPM) software is also an option which allows the user to control the iGM via a computer interface;

Description
The Diacell® iGM Controller employs a fully digital control technology to provide stability and high slew rate when varying the gas pressure in the gas membrane of diamond anvil cells.
It enables the selecting of gas pressure targets, minimum and maximum pressure limits, specific pressure variation slew rates as well as more complex pressure profiles.
The Diacell® iGM Controller is a truly automated gas membrane controller which is particularly suited to experiments where the gas pressure needs to be controlled actively over long periods of time, such as in synchrotron beamlines, for example.
The unit comes with RS232, IEEE, Ethernet and USB ports as standard. The front panel digital touch screen is high resolution VGA.
The system can be controlled remotely with our advanced control and acquisition software the Optiprexx High Pressure Manager. HPM is a Python language based software designed by Almax easyLab and is an additional option when the iGM is supplied on its own.
Low temperature gas membrane cells in addition require the GM Controller Relief Valve Option for safe operation.
Almax easyLab makes extensive use of gas membranes to drive cell pistons in our Diacell® range of DACs.
A gas membrane is rather like a motor tyre with one very thin wall. When pressurised internally, this wall bulges.
Advantages of this type of drive include the ability to apply very small incremental loads, remote operation, and the achievement of higher pressures due to absence of friction associated with bolts. Almax easyLab are able to supply both additional gas membrane drives and control boxes.

FAQs
What are the minimum and the maximum slew rates of the iGM Controller?
The minimum slew rate is set on the 0.02 bar /s in the HPM and on the iGM itself it is 0.01 bar /s.
As for the maximum slew rate of a complete set up (iGM/capillary line/Gas membrane/DAC) this is more difficult to evaluate. From testing done during development, a 210 bar unit will go from 0 to 50 bar in less then a minute but we do not recommend to use such high slew rates for the DAC gas membranes.
