Upper stability island created by auxiliary RF voltage with small amplitude and low frequency  ν =  ω/Ω = 1/10 is investigated. The possibility of operation of quadrupole mass fi  lter with high  transmission 50 % and high resolution about R0.1 = 3000 is demonstrated. Phase shift synchronization,  ion cooling by buffer gas in RF quadrupole, and time fl  ight through fringing fi  eld optimization are  required for achievement of such parameters.
