Carrier Gas Selector (CGS-1050Ex)
This device allows for easy switching between carrier gases, useful for thermal decomposition analysis in air atmosphere.
An inert gas such as He is generally used for the analysis and carrier gas for pyrolysis GC (Py-GC). However, recently air is often used as a carrier gas for pyrolysis analysis in research of environmental pollution control. Theoretically, air can be used in the present devices, but it requires professional expertise and careful modification of devices. The new device, “Carrier Gas Selector” allows switching of gases such as He and air interchangeably while it is connected to the device.
- Combined with Py-GC, it allows flash pyrolysis of polymers under various carrier gasses and evolved gas analysis at up to 1050ºC in temperature-programmed mode.
- With a Multi-Shot Pyrolyzer™ operating in a temperature-programmed mode, varied heating conditions are available to meet your specific needs. Moreover, using the Selective Sampler with various carrier gases, evolved gases from any temperature zone can selectively be introduced into a GC column.
- Instant switching of carrier gases.
The device uses solenoid valves and the dead volume of the flow system is reduced to less than 0.5 mL.
- Protection against Malfunction
When Pyrolyzer is not in use, a protection against operational errors of the front panel switches is implemented so that reactive gases do not flow into GC.
