What issues should be considered when using gas chromatography for detection?

I’m not in this field, but since you asked here, I’ll try to answer a few questions; please feel free to give your criticism. 1. When drawing samples, do so slowly to prevent bubbles from forming; when discharging the liquid, do so quickly. 2. The sampling needle needs to be washed several times. To ensure the authenticity of the sample. 3. For materials that tend to solidify at room temperature, too much solvent should not be added. 4. Pay attention to the temperature of the vaporization chamber and the column temperature; they should not be too high or too low. 5. The velocity of the carrier gas must be controlled, neither too fast nor too slow. 6. The calibration factors for each peak should be determined by comparing with standard samples and the samples to be tested. 7. Before obtaining the results, it is necessary to appropriately process each peak and re-determine its starting and ending points.
