ECL20 is computer controlled, fully automatic electrochemiluminescent instrument. The instrument uses the 16-bit DAC and 16-bit ADC for high resolution and accuracy. The system contains an advanced MCU for digital function generator with a high speed data acquisition circuit and a potentiostat. The compliance voltage is ±12 V, the output potential range is ±10 V and the current range is ±250 mA. The instrument is capable of measuring current down to 100 pA.
The data of the electrochemical and luminescent response are collected simultaneously. The software provides many powerful functions, such as straightforward file handling, extensive experimental control, flexible plots, various data analyses, and efficient digital simulation. Additional features include macro commands, working electrode conditioning, color, legend and font selection, data interpolation, visual baseline correction, data point removal, signal averaging and Fourier spectrum.
The instrument is powerful, automatic and affordable. It is particularly useful for electroluminescent applications.
