tune dissolution

seaa

Hello everyone,

I want to share that I am new to using the ICP-MS, specifically the 7900 model we have in our laboratory, along with the Masshunter software. My usual process involves turning on the plasma and then going to the hardware settings to perform the necessary checks. However, recently I encountered an issue: when trying to make adjustments in the "resolution axis," I receive an error message that reads: "cannot find peaks for optimization. Restored parameters and aborted tune. Check acquire masses in Hardware setting and tune solution."

After analyzing it, it seems that the problem lies in the change of the tune bottle. The new bottle has a concentration of 10ppb, while the old one was 1ppb. By using some of the content from the old bottle, I was able to complete the verification without any issues. Therefore, I believe this problem is related to the difference in solution concentration.

I would like to be able to use the 10ppb bottle correctly. Could someone guide me through the necessary steps to do so? I would greatly appreciate any detailed assistance, as I have never performed this process before.

Thank you in advance for your collaboration!

    Hi seaa,

    the shortest answer is: dilute your 10ppb Tube solution 10 times. Then you will have a 1ppb Tune. 
    you can do it with 1% HNO3 or just ultra pure water.

    i assume that you don’t use an ISIS3 on your instrument. 

    but to be honest, the resolution /axis should definitely work with an 10ppb tune solution. Are you sure, that this is the correct „Agilent“ solution with the following elements: Li; Co; Y; Ce; Tl ?

    Best regards 

    chris

    Good afternoon,

    I want to sincerely thank you for your prompt response. I had some doubts about whether the Tune solution could be diluted. Unfortunately, we do not have ISIS3 available on our team.

    Furthermore, I thought that, despite the Tune having a higher concentration, it should be able to be adjusted. I am attaching the image of the Tune solution that I used.

    Thank you in advance for your assistance.
