Abstract
An automated method for detecting and/or monitoring a state of a degasser of an analyzer is provided, the degasser including a container configured to be evacuated. The method includes obtaining a time series of values indicative of pressures inside the container. The time series spans a period during which the container is evacuated or pressurized. The method further includes determining a liquid level state of the degasser which is determined by an amount of liquid present in the container based on the time series.
Claims19
An automated method for detecting and/or monitoring a state of a degasser of an analyzer, wherein the degasser includes a container configured to be evacuated and a tubing arranged inside the container through which a liquid to be degassed is guided, wherein the tubing is made of a semi-permeable material through which gas contained in the liquid can be removed by effect of the container being evacuated, the method comprising:
- obtaining a time series of values indicative of pressures inside the container, wherein the time series spans a period during which the container is evacuated or pressurized;
- and
- processing the time series to estimate an amount of liquid in the container that has passed through the tubing;
- and
- determining a liquid level state of the degasser based on the estimated amount of liquid, thereby determining a state of the degasser.
