Jena Atomic Absorption Spectrometer, GermanyThe operation steps of the xenon lamp are as follows:

Power on preparation:

Open the main valve of the acetylene cylinder and adjust the gas pressure reducing valve to achieve a gas outlet pressure of 0.1-0.15Mpa.

Turn on the power of the air compressor and adjust the gas outlet pressure to around 0.5 MPa (also known as 0.4-0.6 MPa, which can be adjusted according to the actual situation).

Turn on the power supply of the instrument host and computer, and wait for the instrument to complete self inspection.

Software operation and initialization:

Double click the icon of the operating software to enter the start interface of the application software, and enter the operator information.

Click the "Initialize" command to enter the instrument initialization process. After initialization is complete, click "OK" to enter the system operation interface and wait for the instrument to be ready.

Xenon lamp installation and adjustment:

Click on "Spectral Instrument" on the operation interface, and the Spectral Instrument dialog box will appear.

Click on "Elements" in the "Control" menu of the dialog box, and select the desired cathode lamp (if using a xenon lamp as the light source, select the corresponding xenon lamp element setting).

After selecting the spectral line, click "OK", and then click "Settings" under the "Control" menu. The instrument will automatically move the desired cathode lamp (xenon lamp) to the entrance of the light path.

In the "Energy" menu of the dialog box, click on "Adjust" under "Lamp Adjustment" to adjust the lamp energy, so that the meter reading reaches the appropriate range (such as 700-800V, adjust according to the instrument requirements).

Click on 'Automatic Gain Control' to control the lamp energy and ensure stable light source energy.

Ignition and testing:

Click on "Flame" on the operation interface, and a flame dialog box will appear.

In the "Control" menu of the dialog box, click on "Test Air" and "Test Gas" to check if the gas path is normal. After the air circuit is normal, click "Test End".

Click the "ignition" button to start ignition, and after successful ignition, close the flame dialog box.

Conduct sample testing or draw standard curves according to experimental requirements.

Shutdown steps:

After the sample testing is completed, first clean the injection tube in a cleaning solution (such as spraying in 1% nitric acid solution for 5 minutes, and then spraying in ultrapure water for 5 minutes).

Click "Extinguish" in the "Flame" menu to extinguish the flame, or close the main valve of the acetylene cylinder to burn off the residual gas in the pipe and let the fire automatically extinguish.

Exit the operating software system, turn off the host power and computer power.

Close the main valve of the acetylene cylinder and the power supply of the air compressor, and release the gas from the air compressor.
