OrigaMUX is a multiplexer module developed by OrigaLys, designed for conducting long-term electrochemical tests on multiple samples sequentially. This module is capable of applying a fixed potential successively to up to 8 different cells. Users can control the module by connecting it to potentiostat devices and using the OrigaViewer software, which allows for setting parameters and configurations for each cell individually.
One of the primary applications of OrigaMUX is the study of galvanic corrosion between different metals using the Zero Resistance Ammeter (ZRA) method. This technique is used to measure the electric current between two metals under galvanic conditions, helping users evaluate corrosion levels and protective behaviors of the oxidized metal.
OrigaMUX is a multiplexer specifically designed for sequential (long-term) electrochemical analyses, and is applicable in areas such as corrosion control, fuel cells, microbial fuel cells, electrolysis, galvanic corrosion, surface modification, and more.
Key Features of OrigaMUX:
Maintains constant potential across all cells while sequentially measuring current.
Supports up to 72 cells simultaneously through modular expansion.
ZRA mode support:
Maintains 0 V potential during sequential measurements.
Includes safety features to protect measurements in the event of power failure in this mode.
