This paper outlines key hardware features, front panel operation, maintenance, and troubleshooting.

Step 2: Leak Testing

  • User manual reference: Section 2.5
  • Action: Connect the inlet and outlet tubing. Pump mobile phase at 1.0 mL/min for 10 minutes. Check for wetness around the cell housing.

5.1 Changing the Deuterium Lamp

  1. Turn off power and unplug.
  2. Remove top cover.
  3. Disconnect lamp cable, loosen retaining screws, remove old lamp.
  4. Install new lamp (do not touch glass envelope). Reconnect cable.
  5. Reset lamp hours: func → Lamp Hours → Reset → Enter.

Morning Start-Up (Per Section 3.2)

  1. Turn on detector – Wait for the lamp warm-up (approx. 60 seconds).
  2. Set wavelength – Press FUNC → WAVE A → enter value → ENTER.
  3. Auto-zero – With mobile phase flowing, press ZERO on the front panel or from your chromatography software.
