Atomic fluorescence spectrometer (AFS) has been used in the analysis of As, Hg, Se, Cd, Pb, Sb and Ge in Traditional Chinese medicine.Now the common faults in the use of atomic fluorescence spectrometer are introduced as follows.
1. Communication failure
One of the reasons is to open the software first and then open the instrument. Because the computer software cannot receive the signal transmitted by the instrument under the closed state of the instrument, errors occur.
The correct sequence is to open the instrument first, and then open the software after 30s-1min when the instrument is stabilized.
2. Insufficient argon gas
The remaining amount of argon gas is not enough to support the experimental amount, so it is necessary to replace argon gas in time, otherwise it will be interrupted due to insufficient argon gas during the experiment.
Before the test, the argon gas bottle should be opened and the air flow should be connected. Otherwise, after the sample solution is tested, the solution will backfill and cause corrosion to the pipeline system.
3. Element lamp
Ignite the lamp with an electronic pulse igniter.
4, three-way valve leakage
Replace the three-way valve.
5. Syringe
Replace a new syringe.
6.peristaltic pump and hose
Peristaltic pump head tightness degree is appropriate, do not run without load.If not used for a long time to loosen the pump tube, to prevent the rubber tube extrusion deformation. In addition, the hose (red circle) should also pay attention to the phenomenon of corrosion leakage.
