Abstract：
 The invention relates to a chip type capacity coupling non-touching type electric conductivity detector, which comprises a function signal generator, a micro flow control chip, a signal amplifier, a signal collector and a signal recorder, wherein the micro flow control chip comprises a base sheet and a cover sheet; the base sheet arranges a buffer solution pool and an output solution pool which use the separating channel to connect with each other and a sample pool and a waste liquid pool which are connected with the separating channel; one side of the cover sheet and the base sheet arrange the buffer solution pool, the output solution pool, the sample pool and the waste liquid pool; the other side of the cover sheet comprises 2-10 grooves along to the separating channel; it separately arranges a test electrode in each groove; one of the test electrode is connected with the function signal generator and other test electrodes are separately connected with the signal amplifier.
