A 10:1 mixture of xylene and toluene provides a doublet at m/z 92 (the exact mass of xylene is 92.05813 and toluene is 92.06260). What resolution is required to separate these two (2) peaks? Which mass analyzer would you use?

Jerry Decker

Xylene has an extra methyl group making the molecular weight around 106.
