Comprehensive Analysis of Spectrometers: Principles, Usage Methods, Common Faults, and Repair Techniques (Spectral Analyzer, Infrared Spectrometer, Raman Spectrometer, Fluorescence Spectrometer, Direct-Reading Spectrometer, UV-Vis Spectrometer, Fluorescence Spectrometer)

I. Spectrometer Fault Handling

1. Invalid Detection, No Data Output:
   • Replace or upgrade the light source equipment.
   • Repair or clean the detector.
   • Realign the optical path.
   • Fault Causes: Insufficient light emission from the source, damaged or dusty detector, misaligned or shifted optical path.
2. Optical Path Obstruction:
   • Clear the sample or optical path.
   • Check for damaged components or dust in the optical path and clean or replace as necessary.
   • Fault Causes: Sample residue in the optical path, blockages such as damaged components or dust.
3. Vacuum Pump Not Starting:
   • Ensure consistency between pump and oil models, and regularly replace pump oil.
   • Adjust indoor temperature to avoid excessively low temperatures.
   • Check and manually start the pump motor via the analysis software.
   • Fault Causes: Poor viscosity or incorrect model of pump oil, temperature-related issues, control signal problems.
4. Sudden Loss of Negative High Voltage:
   • Try unplugging and replugging the second ground wire of the control box; if unsuccessful, consider restarting the instrument.
   • Fault Cause: Vacuum value not rising for an extended period.
5. Low Light Intensity:
   • Clean the condensing lens.
   • Clean the slit.
   • Replace the corresponding photomultiplier tube.
   • Fault Causes: Dirty condensing lens, dirty slit, degraded performance of the photomultiplier tube.
6. Unstable Instrument Analysis Data:
   • Check and replace the rear fan of the instrument if necessary.
   • Fault Causes: Poor temperature control in the instrument’s vacuum chamber, faulty rear fan operation.
7. Poor Communication Line Contact Leading to Computer Crash or Program Error:
   • Reconnect the communication line.
8. Exhaust Blockage:
   • Replace the exhaust pipe with a transparent plastic tube and regularly purge the exhaust line.
   • Fault Causes: Blocked argon exhaust line, debris in the lower bend of the spark chamber, debris at the inlet of the argon filter.
9. Power, Connection, or Software Issues:
   • Check for proper power connection, damaged or loose power cords.
   • Ensure correct and undamaged connection of cables.
   • If software issues occur, attempt reinstallation or updating.
10. Other Maintenance and Calibration:
    • Regularly clean the optical components of the spectrometer and perform calibration to ensure accuracy.
