1 , 2 There is an increasing trend towards the development of small and miniature portable quadrupole mass spectrometers for point of use applications. 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 Sensitivity is an important and longstanding constraint, especially for miniature instruments. 11 To retain performance with small or micro footprint instruments, highly accurate modelling of QMF behaviour for various design geometries is advantageous since it is capable of streamlining experimental prototype testing.
