WebThe quadrupole mass analyzer propels ions using opposing RF and current fields at its poles. A quadrupole mass analyzer works by combining a radio frequency (RF) alternating current (AC) potential with a direct current (DC) potential over four electrodes, or poles, to create the electric field that sample ions pass through. WebThepotential conﬁgurations for ion and electron energy discrimination are sketched in ﬁgures 2(b) and (c), respectively. The analyzer (including G 0,G 1,G 2and C) is enabled to ﬂoat at the ac component of the applied bias signal. This is achieved by means of high impedance low-pass ﬁlters.
