Configuration
• COM Port for ALS
Specify the COM port to which you want the Autosampler connected. Normally
this is COM1.
• Racks (ASX500 or ASX100)
For the ASX500, the racks are, from left to right, identified as Rack ID 1, Rack
ID 2, Rack ID 3, and Rack ID 4.
Note that if the setting is wrong the Autosampler needle will not go to the correct
position.
• Sample Tray (I-AS)
Select the sample tray that will be used.
• Sampling Depth (I-AS)
In the locations below, set the travel distance for the I-AS arm from its highest to
lowest positions. For more information about the Sapmling Depth, refer to the
Integrated Autosampler Manual.
• Enable ESC Mode (I-AS)
Check this to enter the ESC (escape) Mode. For more information about the ESC
Mode, refer to the Integrated Autosampler Manual.
Click OK when the configuration of the Autosampler has been completed.
6Set prohibited masses.
Insert prohibited masses to protect the detector (EM) from large signals caused by
Oxygen, Argon, Nitrogen, Hydrogen, and other polyatomic ions.
CAUTION You should not modify the prohibited masses setting except for specific applications
(For example, measurement of 40Ca with cool plasma condition). If under normal
plasma conditions, large signals will cause the rapid deteriation of the detector (EM).
