Description

A kind of ion migration spectrum micro current signal take-away device
Technical field
Patent of the present invention relates to Instrumental Analysis field.Be specially a kind of signal ejector for ion mobility spectrometry.The feature that this device has gas circuit sealing, pogo pin contacts draws signal, can improve the performances such as antidetonation, improves system reliability.
Background technology
A major issue in the design of ion mobility spectrometry migration tube is the acceptance of pole weak signal (receive and pacify level) and effectively draws.Usual signal lead-out wire adopts the modes such as welding, can Long-Time Service and there will not be serious problem in quiescent operation environment in laboratory conditions.But the problem under other conditions, as then easily occurred coming off in the dynamic environment such as portable, hand-held.
Pressure electric shock lead-out mode widely uses at electronic applications.In ion mobility spectrometry migration tube, require to possess air-tightness and resistance to elevated temperatures simultaneously, and keep clean zero effusion thing, the design of common electronic applications can not meet the demands completely.
The structure that patent of the present invention adopts well solves this problem.
