Description
Technical field
The present invention relates to a kind of printed circuit transference tubes.
Background technology
Transference tube is the Main Analysis component of ion mobility spectrometry, is mainly alternately superimposed by electrode retaining collar and dead ring
After form cylindrical pipe, place ion take-up reel reception in one end of pipeline and wait for measured ion, the other end is equipped with ion door gear,
Control waits for that measured ion enters transference tube, and transference tube need to be generated by electrode retaining collar along migration tube axial direction when analysis
The electric field of even variation, common electric field strength variation is 220~240V/cm, generally uses becket addition polymerization tetrafluoroethene
Or ceramic ring, as the insulating layer between becket, common metal ring thickness is in 1mm or so, thickness of insulating layer 6mm or so.And
The thickness and density of electrode retaining collar directly influences the uniformity of the electric field change in migration tube, and electrode retaining collar is thinner, electrode retaining collar it is close
Degree is bigger, is more conducive to form the stable uniform electric field of variation in transference tube, the electric field of even variation is conducive to carry
The separating effect of macroion migration spectrum and sensitivity.Just because of this, metal ring electrode edge is mitered into wedge by many researchers
Shape improves the uniformity of electric field with this, but the effect that the method can obtain is limited to obtain relatively frivolous electrode edge, electricity
Pole thickness still in grade, can not greatly improve the performance of ion mobility spectrometry, and electrode and dead ring are alternately installed,
It is required that the machining accuracy of dead ring and electrode retaining collar is high, the mismachining tolerance that the mismachining tolerance of electrode is superimposed with dead ring to assemble
Error greatly increases, and the increase of this error, also increases the non-uniform possibility of electric field in transference tube.Meanwhile adding
The cost is relatively high for the uniform metal electrode film of work thickness or ceramic electrical pole piece, and especially ceramic electrical pole piece yield rate is relatively low,
The cost is relatively high for product.
