An electrochemical sensor based on hierarchical nickel ...

The new prepared nano-modifier was practically used to co-detect electrochemically sunset yellow and tartrazine dyes. Potent sensitivity and acceptable selectivity were obtained for the produced In 3+ /NiO RLHNSs to co-detect both the food colorants, thus providing oxidation peaks in differential pulse voltammetry (DPV) with a peak potential separation of ca. 190 mV.

2GIG CO3 - Wireless Carbon Monoxide (CO) Detector - Alarm Grid

The detector is 3V battery powered (CR123A Panasonic battery) and outfitted with an electrochemical carbon monoxide sensor. Like any CO detector, there is a 5 year 'end-of-life' from the manufactured date. When the detector has reached the end of its life, the yellow LED blinks once every 23 seconds and there is a chirp from the keypad every 45 seconds. After 12 hours the panel will issue a ...

The Theory Behind Carbon Monoxide Electrochemical Sensors ...

· Since electrochemical sensors work with the same theory but different materials, we have described only how the CO sensor works in this application note. The carbon monoxide sensor consists of three electrodes immersed in a liquid electrolyte (a non-metalic liquid that conducts electricity, usually through acids or dissolved salts). The three electrodes are the working electrode, the reference ...
