Description
Technical field
The utility model relates to mass spectrometer, particularly relates to the ion transport device in mass spectrometer, and cation can be made to be deflected through and block electrons, photon and neutral particle.
Background technology
Mass spectrometer is a kind of instrument measuring ion mass-to-charge ratio, and the ion produced by ion source arrives mass analyzer through overshoot transmitting device, signal detected, to obtain the information of mass-to-charge ratio after selecting matter by detector.The effect of ion deflecting transmitting device has two, and one is that two is that block electrons, neutral particle and photon are to improve the final signal to noise ratio of instrument at difference vacuum cavity transmission ion.
In current mass spectrometer, the implementation of ion deflecting transmitting device is mainly divided into three kinds, and one is cylinder baffle-type, and one is normal deflection formula, also has one to be off-axis conveying type.In the ion deflecting transmitting device of cylinder baffle-type, circular baffle plate is put at tubular ion lens center.Ion, when scioptics, is subject to the effect of electric field force, and first outwards disperse, to walk around baffle plate, more again focus on, fly out deflection transmitting device.And for photon and neutral particle, due to not by the effect of electric field force, then directly to strike on baffle plate and kinetic energy loss, cannot ion deflecting transmitting device be passed through.This kind of mode structural design is simple, but ion transmission efficiency is low.The structure that typical cylinder baffle-type ion deflecting transmitting device has Perkin-Elmer company to use on its Elan series ICP-MS.
For normal deflection mode, its main operation principle is, ion is by a deflecting electric field region, be subject to the effect of electric field force and depart from the original direction of motion, and finally deflect 90 ° when outgoing, and photon and neutral ion be not by electric field force effect, flies along former road.Although this mode structure is simple, because ion transfer path is right angle, be unfavorable for the miniaturization of instrument.The quadrupole ion deflector that typical normal deflection formula ion deflecting transmitting device has Extrel company to produce and the deflection structure that Varian company adopts on its ICP-MS product.
Off-axis transmission means refers to that ion transfer fore-and-aft direction is constant, but transmission path can offset to some extent.This mode can be realized by off-axis guide bar, and ion is travelled forward along off-axis guide bar under the constraint of rf electric field; Or adopt the electrostatic lens of given shape and direct voltage, ion does off-axis motion under this electric field.
In addition, for basic electrostatic lens, it has focussing force to ion beam, focuses on similar with optical lens to light beam.And optical lens can deflect the light beam from axle, similar electrostatic lens also has deflecting action for the light beam from axle.
