|Title:||Contactless Differential Conductivity Detection|
|Published:||October 12, 2008|
|Abstract:||We propose a new technique, contactless differential conductivity detection (CDCD,) to improve the detection limit of contactless conductivity detection for capillary and microchannel electrophoresis. By exploiting a 3-electrode differential configuration, CDCD greatly reduces the dominant noise source in contactless conductivity detection: temperature fluctuations within the measurement system. This will be a particularly important feature for high-conductivity samples, which are most susceptible to thermal noise. The reduced sensitivity of CDCD to temperature fluctuations and its potential suitability for low-power operation will also make this an excellent candidate for field-portable and point-of-application uses where optical detection strategies may be more difficult to implement.|
