WE material: gold, platinum, silver, copper, iron, nickel, cobalt, chromium, tantalum, irridium, rhenium, magnesium, palladium, zirconium and others
*Selection of sensor electrode materials other than those listed above is possible upon agreement with the customer.
The sensor is made on a corundum ceramic base. Working, reference and auxiliary electrodes are applied to this surface. Working, reference and auxiliary electrodes are made of different materials. At the end of the sensor there is a contact field that is connected to the active part by silver conductive paths that are covered with a dielectric protective layer. The working electrode of the sensor with a diameter of 2 mm is made of a material of guaranteed purity of up to 99.99 % depending on the selected material– standard layer thickness 0.0125 mm.
We also offer a working electrode made of polished gold AC1P.W*.R*, with homogenous surface with roughness less than 1 µm.
We also offer activated graphite sensors on customer request.

FC2.TL.* PMMA Flow Cell
Read moreThe flow cell enables the use of Screen printed sensors in a flow through arrangement.
The flow cell is suitable for sensors of type AC1, AC2, CC1, CC2 and CC3.
The Screen printed sensor is inserted into the slit of cell and tightened by closing of the door. The cell ensures the wall-jet flow around the working electrode and it is optimised so that no air bubbles cumulate in the cell. The cell contains also the contact and output cable.
With the sensors enclosed in a flow cell, it is possible to measure semi-automatically or automatically using a pump or liquid switch for sample supply. Under such conditions, maximum measurement reproducibility is ensured.
