1. Timely replacement of the gas chromatography column interface seal.

Avoid reusing the same sealing gasket; even when reinstalling the same column, it's best to replace it with a new one to ensure the gas chromatograph operates with higher efficiency and better sealing.

Follow the procedures outlined in the gas chromatography instrument's manual.

When inspecting a gas chromatograph, ensure all parts are accounted for and that the manuals are complete. Prior to operating the instrument independently, carefully read the product manual for the Chengzhi Gas Chromatograph and follow the procedures strictly.

3. Prepare a chromatography column test standard sample for the gas chromatograph.

Before using a gas chromatograph column, it is essential to first age the column, as its performance is a critical factor in ensuring accurate analysis results.

4. Regularly replace the inlet port gaskets and promptly clean the sample syringe, or opt for disposable syringes whenever possible; regularly inspect and clean the inlet port liner.

5. Utilize reliable pressure regulating valves and replace parts individually.

It's crucial to develop good habits when operating a gas chromatograph.

6. Utilize gases with the required purity.

Especially, the carrier gas must be of high purity grade to avoid interference with analysis and contamination of the chromatographic column or detector.

Maintain comprehensive records of instrument usage and rigorously inspect the gas chromatograph in accordance with the calibration procedure cycle.

8. Regularly replace the gas purifier filling, gas drying unit, and deoxygenation device in the gas chromatograph.
