ChromaTCD

The ChromaTCD is an automated gas chromatography system integrated with a Thermal Conductivity Detector (TCD). It is specifically designed for the analysis of permanent gases and/or hydrocarbons. It is ideal for high-precision applications requiring continuous monitoring and automated data processing in industrial and laboratory settings.

Operating Principle

• Automated Sample Injection: The sample is injected into the system through an automated loop, ensuring high precision and repeatability.
• Gas Separation: Permanent gases and light hydrocarbons are separated using a metal analytical column (packed or capillary) within a stable thermal chamber.
• Detection via TCD: The TCD detects changes in thermal conductivity between the carrier gas (Helium or Hydrogen) and the sample gases exiting the column, producing accurate signals.
• Data Analysis: Results are collected and processed using Vistachrom software, providing detailed reports on retention times, concentrations, and chromatograms.

Key Features

• Non-destructive TCD Detector: High sensitivity with detection levels from ppm to %, unaffected by matrix interference.
• Continuous Operation: The system operates 24/7 automatically after initial setup.
• Automatic Calibration: Integrated calibration valves and data validation system.
• High Stability: Retention time drift of less than 0.6% over 48 hours.
• Low Maintenance: Minimal gas consumption, long detector lifespan, reducing maintenance requirements.
• Smart System: Features customizable alarms and over 10 years of data storage capability.

Optional Add-ons

• Carrier gas filters (for UHP analysis).
• Hydrogen and Nitrogen generators.
• Flow selectors (supporting up to 16 channels).
• Automatic sample suction pumps.
• Wall-mounted cooling or heating systems.
• Explosion-proof versions (ATEX/IECEx Zone 1, 2).

Vistachrom® Software

• Fully integrated remote monitoring and control.
• Storage and management of chromatograms and reports.
• Supports alarm threshold settings and automatic notifications.
• Data export through various protocols (MODBUS, RTU, TCP/IP).

Practical Applications

• Oil & Petrochemical Industry: Quality control of gases and impurity detection in production processes.
• Environmental Monitoring: Measuring emissions and assessing odor impact.
• Industrial Production: Monitoring gases in production and wastewater treatment processes.
• Cleanrooms: Ensuring environments are free from harmful contaminants.
