Abstract An extended mass range covering m/z 70–240 in a microscale (r0 = 800 μm) planar linear ion trap (μPLIT) is demonstrated, enabled by optimization of dipole resonance ejection conditions without increasing trapping voltage or frequency compared with prior results. This represents a significant increase in the measureable mass range of coplanar traps and microscale traps in general. Performance was demonstrated using headspace vapor of octafluorotoluene (OFT) as well as mixture of perflurotributylamine (PFTBA) and OFT. Typical mass resolution of approximately 3 Da (FWHM) was observed.
