The gas chromatography laboratory must be well-ventilated to ensure safe and efficient operation. The ambient temperature should remain between 5°C and 35°C, with relative humidity not exceeding 85%. Installing an air conditioning system is highly recommended to maintain stable environmental conditions. Smoking or any form of open flame is strictly prohibited in the lab, as it poses a serious fire hazard. Additionally, avoid placing the instrument near strong magnetic fields or corrosive gases, which can interfere with its performance. Gas cylinders must be stored separately from the lab area to prevent accidents.
The power supply for the gas chromatograph should have sufficient capacity—ideally around 10V·A—and should not share a circuit with high-power equipment such as ovens or heaters. A reliable and properly grounded electrical system is essential for both safety and instrument stability. It’s also advisable to ground both the power supply and the instrument casing to minimize electrical interference and improve performance.
The workstation where the gas chromatograph is placed should be sturdy, spacious, and level to ensure ease of use and stability. A cement platform is often used to provide a solid base. The platform should be positioned 0.5 to 1.0 meters away from the wall to allow for convenient wiring and maintenance access.
When using detectors like TCD (Thermal Conductivity Detector) or ECD (Electron Capture Detector), proper waste gas disposal is crucial. Connect the instrument’s vent to an external exhaust system via piping to safely remove any residual gases and maintain a clean working environment.
Always be cautious when handling the instrument’s power cover or side panels, as there may be high voltage inside. Before performing any maintenance, always unplug the power cord to prevent electric shocks and ensure personal safety.
After the instrument has been heated, even if the oven and column have cooled down, the injector and detector connections may still retain heat. Always wear insulated gloves or take other protective measures to avoid burns during handling.
The detector housing should remain closed at all times to protect against temperature fluctuations that could affect instrument stability. Never open the column oven door while the instrument is in operation, as this can lead to inaccurate results or damage to the system.
If the gas chromatograph will not be used for an extended period, it is important to periodically power it on and check its performance. This helps maintain the reliability and functionality of the instrument, ensuring it is ready for use when needed.
