Dead time correction

You can use a 50 ppb solution for that. 

You will need a high and low concentration. The typical dead time standards are 50ppm and 1ppm Er. If you get an error during the dead time adjustment the signal is too high or too low you may need to adjust these concentrations. 

Hi Cheltajc,

Thanks for your reply. I will try 50ppb and 1ppm first.  

Hi Emretoprak,

Thanks for your reply. I will start with this concentration.
