Atomic fluorescence spectrometers are mainly used for the analysis of metal elements such as arsenic (As), mercury (Hg), selenium (Se), cadmium (Cd), lead (Pb), antimony (Sb), and germanium (Ge) in traditional Chinese medicines.
- Communication Failure
- Cause: One of the causes is turning on the software before the instrument. When the instrument is off, the computer software cannot receive the signal transmitted by the instrument, resulting in an error.
- Solution: Follow the correct sequence: turn on the instrument first, wait for 30 seconds to 1 minute until the instrument stabilizes, then open the software.
- Insufficient Argon Gas
- Cause: The remaining amount of argon is not enough to support the experiment. If argon is not replaced in time, the experiment will be interrupted with a prompt of “insufficient argon”.
- Solution: Replace argon promptly when its level is low. Before the test, open the argon cylinder first to allow the gas to flow through the system. If you skip this step and start measuring the sample solution immediately after turning on the instrument, the solution will siphon back, causing corrosion to the pipeline system.
- Element Lamp
- Operation: Use an electronic pulse igniter to activate and turn on the element lamp.
- Three-Way Valve Leakage
- Solution: Replace the three-way valve.
- Syringe
- Solution: Replace with a new syringe.
- Peristaltic Pump and Tubing
- Operation & Maintenance: Adjust the pressure head of the peristaltic pump to an appropriate tightness, and do not operate the pump under no-load conditions.
- Long-Term Storage: If the peristaltic pump will not be used for a long time, loosen the pump tubing to prevent the tubing from being squeezed and deformed. In addition, pay attention to the tubing (marked with a red circle) for corrosion and leakage.
