Abstract:
1. A contactless conductivity detection cell comprising: a microfluidic chip having a channel defined by channel walls, first and second emitting electrodes, and first and second receiving electrodes, a first ground plane between the emitting electrodes and the receiving electrodes, a grounded metal housing containing the emitting electrodes, the receiving electrodes and the first ground plane, and a second ground plane configured to shield the emitting electrodes and the receiving electrodes from interferences from electronic components housed in the grounded metal housing, wherein the first emitting electrode and the first receiving electrode are adjacent a first channel wall, and the second emitting electrode and the second receiving electrode are adjacent a second channel wall, the second channel wall being opposite the first channel wall; wherein the first emitting electrode and the first receiving electrode are arranged adjacent one side of the channel and spaced from the channel; and wherein the second emitting electrode and the second receiving electrode are arranged adjacent an opposite side of the channel.
