ICP MS 7900 Error 1218.

Hello, we have the following problem. Our ICP MS 7900 ignites plasma, then burns for about 10 seconds and then goes out. The device shows error 1218 (Plasma was shutoff (Plasma RF monitor)).

Would any of you have such a problem? What have you done? Could you solve the problem yourself? If yes how? I thank you in advance for your help.

  • Is this sudden happen, or after a maintenance or some other hardware of software setting change?

    There are many reasons possible for this plasma shutoff error. The ICPMS MassHunter Help software give you several possibilities. Please check the below help list first. most likely there is a air leak- or wrong rf matching causing this error. This is because the plasma is lit and shut off when the nebulizer flow comes in and the latest tune values are implemented. however please check the whole list.

    if no problem found, please contact your local service representatieve for faster response.
