RECEPTION OF THE IDENTICAL RESOLVING ABILITY ∆М IN THE QUADRUPOLE MASS SPECTROMETER IN A WIDE RANGE OF MASSES
The method of reception of identical resolving ability ∆<i>М</i> = const in an analytical quadrupole mass spectrometer in a range of masses 2-500 u is described. It is achieved by the maintenance of strictly certain law of change of precision voltages relation changes - constant component <i>U</i> to the amplitude of a variable <i>V</i> voltage component <i>φ </i>= ± (<i>U </i>+ <i>V </i>cos<sub> </sub><i>ωt</i>), applied to the quadrupole analyzer electrodes. The method of precise <i>U</i>/<i>V</i> relation measurement with the resultant curve which can be reproduced with high accuracy that maintains target electronic parameters of the HF-generator strictly constant and at the qualitative analyzer maintains ∆<i>М</i> = const is suggested.
