非接触式电导检测器
非接触式电导检测器（ccd）与普通的电导检测器相比，有以下几个优点：
1.安装非常简单，不需要与毛细管口对准连接等复杂操作。
2.由于电极不与电泳缓冲液接触，噪音小，检测灵敏度*的提高。
3.也正因为电极不与电泳缓冲液接触，在电泳过程中，电极不会有产生气泡等问题。

the tracedec contactless conductivity detector (ccd) is based on two metal electrodes, which are placed around the separation capillary, which can be of any non-conducting material (e.g. fused silica, peek, teflon). after an ac voltage is applied to the actuator electrode, the current passes the capillary wall, the detection gap between the electrodes inside the capillary, and back to the pick-up electrode. the signal is then further amplified and processed. this detector can be coupled to any prince system without using any tools.
some features of the tracedec contactless conductivity detector
simple operation conditions
ccd offers a number of advantages over standard conductivity detection. it is very easy to set up, because the electrodes don"t need to be carefully aligned within the microscopic ce channels. secondly, because the electrodes aren"t in direct contact with the electrophoresis buffer, the background noise is greatly reduced, thereby increasing sensitivity. thirdly, the lack of direct contact between the electrodes and the buffer also prevents bubbles being cr-eated via electrolysis.
