typical vacuum condition of PE Elan 5000

I am trying to set up an Elan5000 ICPMS and I have questions about the vacuum system and ion optics.
what are the typical vacuum pressures in the quadrupole chamber, the ion optics chamber and the interface area before and after igniting the plasma?
After ingiting the plasma, the pressures of our ICPMS at these three chambers are 4.85E-3pa, 4.5E-1pa and 2.25E+2pa. I can't get any signals under this condition, so I am wondering if the pressures are too high.
If the pressures are all right, what will be the possible reasons that I can not get signals?
In order to optimize the signal, what are the typical voltages applied on the P lens, entrance and exit lens?

Thank you very much for your help!

Long time ago that I worked with this Elan5000. As I remember, the default settings for these Einzel lensens where 25 for all 4 digipotts. In X/Y mode you can monitor the low, middle and high masses to see the effects of changing the lens voltages. In most cases this was done to get some more sensitivity for the low mass analytes.
What I don't understand is your question about the vacuum. The Elan5000 has only one vacuum chamber and it will only monitor the vacuum in "base" (valve closed) and "running"(valve open) mode. The valve can be opened in auto mode or manually with the switch. Furthermore the vacuum is expresses in Torr and both where normally in the range of 10-6 and 10-5. Even when I convert Pascal to Torr, it looks like you have a big vacuum problem and that might be the reason that you have no counts at all. Sorry
