Latest Patents

One of Lagois's latest patents is an electrochemical multigas sensor. This invention features an electrochemical measuring cell designed for the simultaneous detection of various gas components in a gas sample. It includes multiple measuring electrodes positioned behind a diffusion barrier, along with a common reference electrode and counterelectrode in an acid electrolyte. The sensor improves service life for detecting oxygen and carbon monoxide by utilizing a reference electrode made from a sintered mixture of metal and its metal oxide, preferably from the platinum or iridium groups. The potential of the CO-measuring electrode is set between 0 to 300 mV, while the O2-measuring electrode is set between -300 and -800 mV.

Another significant patent is a sensor for capacitively measuring pressure in gases. This invention allows for capacitive measurements of gas pressure without the need for deformable parts. The sensor consists of two measuring electrodes that define a capacitor and are arranged in a spaced relationship. This design enables long-term drift-free measurements, even with minimal electrode spacing, making it suitable for miniature sensors. The intermediate space between the electrodes is accessible to the gas being investigated and is maintained by electrically insulating spacers.
