非接觸式電導檢測器（ccd）與普通的電導檢測器相比，有以下幾個優(yōu)點：
1.安裝非常簡單，不需要與毛細管口對準連接等復雜操作。
2.由于電極不與電泳緩沖液接觸，噪音小，檢測靈敏度*的提高。
3.也正因為電極不與電泳緩沖液接觸，在電泳過程中，電極不會有產(chǎn)生氣泡等問題。
檢測限：10-40ppb

精    度：±0.5 ºc
操作溫度：10-40 ºc

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.
