For the insufficient vacuum issue of Agilent 6546 high-resolution mass spectrometer, professional repair steps typically include:

1. Vacuum gauge status check: Confirm whether the pressure is decreasing normally to eliminate vacuum gauge malfunctions.
2. Vacuum pump maintenance: Inspect the working state of the vacuum pump; replace pump oil, clean the pump body, or repair faulty components as needed.
3. Vacuum chamber component cleaning: Clean contamination-prone parts such as the ion source and pre-quadrupole, since their contamination can affect vacuum stability.
4. Carrier gas troubleshooting: Close unnecessary gases (e.g., hydrogen) to avoid interference with vacuum performance.
5. Seal inspection and replacement: Check for leaks in seals and replace worn or damaged seals promptly.
