Carrier Gas Selector (CGS-2050E/1050Ex)

NEW

Analysis of gases generated under various reaction gas atmospheres

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.

The new Carrier Gas Selector (CGS-2050E) retains the core performance of the previous model (CGS-1050Ex) while offering enhanced operability and ease of use.

*The previous model (CGS-1050Ex) will be discontinued as of December 31, 2025.

  • Features

  • Specifications

1. Versatile for chemical reaction and thermal oxidation testing
Chemical reaction tests in a heated furnace with any carrier gas, as well as thermal oxidation tests under an oxygen atmosphere, can be performed. Furthermore, by using the Selective Sampler for evolved gas analysis, gases evolved at any temperature zone using various carrier gases can be selectively introduced into a GC column for effective separation and analysis.

2. Instantaneous switching of carrier gases
The flow path is designed with minimal dead space (0.5 mL or less), allowing rapid and seamless switching between carrier gases.

3. Automatic control
It can be operated in conjunction with the Multi-Shot Pyrolyzer (EGA/PY-3030D), Auto-Shot Sampler, MicroJet Cryo-Trap, and Selective Sampler.

Usable carrier gases:
Two gases are selected from He, N2, Air, O2, etc. (one must be an inert gas such as He or N2)

Carrier gas switching:
Flow path switching by solenoid valve. MANUAL mode: Manual switching.
AUTO mode: Automatic control via Multi-Shot Pyrolyzer software.

Power requirement:
100 - 240 VAC, 40VA (support for a wide range of power voltages)

Supported GC model:
Agilent 8890/8860GC, PerkinElmer Clarus 690, SCION 456, Shimadzu GC-2030/2010,
Thermo Fisher TRACE 1610/1600/1310/1300 GC
