  • Mass spectrometery calibrant liquid container level sensing
    Patent number: 11982654
    Abstract: Determining a level of a liquid in a container is described. In one aspect, a container includes a calibrant liquid used for calibrating a mass spectrometer. A conductive layer is placed to float upon the calibrant liquid, and a circuit board with electrodes is arranged around the container. A controller circuit then drives and measures various electrodes to first identify which two electrodes the level of the calibrant liquid is between, and then subsequently identify a more precise location for the level between the two electrodes.
    Type: Grant
