Детектор электрохимический AZURA ECD 2.1

Product Description High Sensitive Electrochemical Detector for Liquid Chromatography single cell control, with DC, pulse and scan mode Compact Thermostat included 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 Faradays 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. The AZURA ECD 2.1 is controlled by software packages ClarityChrom and Chromeleon Puls mode Measuring range 10 pA-200 &mu,A in steps of 1, 2 and 5 Filter (cut off) Advanced Digital Filter, 0.5 -0.001 Hz in steps of 1, 2 and 5 Pulse times t1: 100-2000 ms, t2: 0-2000 ms, t3: 0-2000 ms in steps of 10 ms Data recording 20, 40, 60, 80 and 100 ms DC mode Measuring range 10 pA-200 &mu,A in steps of 1, 2 and 5 Filter (cut off) Advanced Digital Filter, 0.5 -0.001 Hz in steps of 1, 2 and 5 Noise &lt, 2 pA with dummy cell Scan mode Measuring range 10 pA-200 &mu,A in steps of 1, 2 and 5 Scan speed 1-50 mV/s in steps of 1, 2 and 5 Scan cycle half, complete, continuous Detection Detector type Electrochemical detector Version DC, pulse, scan operating modes Detection channels 1 Working potential -2.0 V to +2.0 V Maximum data rate 10 Hz Autozero triggered via key, TTL, RS-232 Heated zone Thermostatting oven included Temperature range from 7C above ambient temperature to 45C Communication Control Parametric control and data-acquisition via LAN port (USB service port) General Dimensions 220 x 440 x 440 mm Weight 14,6 kg without column and flow cell
