GAS SWITCHERS

Qubit Systems' G243 4 Channel Gas Switcher is designed for use in 4 channel gas exchange systems in which gases from sample chambers are selected sequentially for analysis. In Open Flow Mode the Gas Switcher takes gas from all sample chambers, selects one line for analysis and vents the other lines to the atmosphere. The gas is then either selected for analysis or vented to the atmosphere. In Stop Flow Mode, the switcher seals the sample chambers for a user-defined period. The chambers are then flushed sequentially for gas analysis to provide time-integrated measurements of gas exchange rates. Plumbing the system for either mode is fast and easy.

Qubit's C950 Gas Exchange Software controls the switcher, allowing any channel to be chosen for analysis in any sequence at a user defined frequency. Switching between reference and sample channels results in easy tracking and correction for any incidence of baseline drift. The Gas Switchers can be purchased with optional C250 Gas Switcher Software for stand-alone use. The C250 software provides all the switching functionality of Qubit Systems' C950 Gas Exchange Software, but allows the switcher to be used in conjunction with any gas exchange system and/or data acquisition software you already possess. The switcher may also be provided with an on-board micro for use without a separate computer.

Each of our instruments is designed so that they can work with gas exchange and data acquisition systems other than those manufactured by Qubit Systems.

The Switcher is also available in an 8 channel version.
