ChromaTCD is an automated gas analysis instrument used in industry. Gas samples are introduced into the system through a sampling loop and then injected into the analytical column to perform component separation. The system can employ either packed columns or capillary columns.

Application Example:

• The first analytical column separates CH₄ and CO₂ from a mixed peak containing Ne, H₂, O₂, N₂, and CO. The remaining compounds are further separated on a second column.
• The system operates under isothermal conditions.
• The Wheatstone bridge of the Thermal Conductivity Detector (TCD) is supplied with a stable voltage, and the automatic injection valve ensures that the sample injection is performed accurately.
• In the standard configuration, column temperature and system cleaning methods can be programmed.

The Vistachrom software allows for real-time data monitoring and storage on a computer. Additionally, the software supports recalculation tools, calibration, data export, and measurement method setup. The system is capable of calculating retention time, peak area, mass, or concentration of the analyzed components.
