Articlename: Electrochemical Detector AZURA ECD 2.1

High Sensitive Electrochemical Detector for Liquid Chromatography


single cell control, with DC, pulse and scan mode

With its measurement frequency up to 100 Hz, this electrochemical detector is specially designed for super-fast highly sensitive and selective measurement of oxidisable and reducible substances in (U)HPLC. The AZURA ECD 2.1 comprises of a thermostat-controlled Faraday's cage, accommodating column and flow cell. The AZURA ECD 2.1 unites the three operating modes DC, Pulse and Scan in one instrument. The DC mode covers about 90% of all applications. The pulse mode is important for PAD (Pulsed Amperometric Detection) of e.g. carbohydrates. The scan mode is used to obtain a voltammogram in method optimization. A digital low-pass filter provides an excellent signal-to-noise ratio. For highest sensitivity, the SenCell flow cell is recommended. The correct flow cell can be chosen from a broad variety of flow cells after our advice.
