Full spectrum on startup

Hi all

I have run a full spectrum on startup to check for contaminations. I was surprised with the high counts measured for most elements. 

Does that look right? Am I missing something? The first line is the full spectrum and below is the calibration run after it.

  • Hi elementallab, 

    I would be surprised if this was contamination in the tune solution, we use the agilent 10ug/L Ce, Tl, Y,Co and Li tune solution. 

    This is our settings for start up, but it does not allow me to change the solution at the tune/ISTD column, is there any way I can do it elsewhere? Or could I select full spectrum only and use autosampler position in the top bar? 

  • Hi,

     Probably  it was not clear in previous message. I see now that you use ISIS, so contamination could be somewhere in capillarity tube or valve – to check this you can test tune like sample in other vial  in auto sampler and look in signal monitor for problematic masses counts.
