This content is a preprint and has not undergone peer review at the time of posting.


We demonstrate chemical noise filtration by differential mobility spectrometry (DMS) ahead of an ion trap mass analyzer. Use of DMS enables 10x improved accuracy in the isotope ratio measurement made for a sample of natural uranium.
