Fast all the elements uncalibrated, but zinc calibrate

Hi everyone,

I measured some methanol samples, with ethanol diluted. Most of the elements are uncalibrated, but zinc is calibrated.

I have two questions:

1. I thought it is because of the transportation of sample. But when the sample was not stable transported, why did I get the calibrated zinc? What could be the problem here?

2. When I want to do the elements screening, to measure many elements together, is it the reason of wavelength interference? If I did not choose so many elements, is there still wavelength interferece?

Thank you very much!

Best regards
