摘要
A method for detecting the presence or absence of a gas bubble in an aqueous liquid is provided comprising providing an amperometric sensor positioned within a measuring chamber, wherein the amperometric sensor is configured to determine the concentration of a gaseous component dissolved in a liquid, the amperometric sensor comprising a sensitive region; positioning the liquid in the measuring chamber; taking at least one first measurement value of the gaseous component from a first portion of the liquid after a predetermined response time, the first portion located in the sensitive region of the sensor; moving the liquid along in the measuring chamber, such that a second portion of the liquid, which had previously been located outside the sensitive region of the amperometric sensor, is positioned in the sensitive region; taking at least one second measurement value of the gaseous component from the second portion of the liquid; and detecting the presence or absence of a gas bubble by comparing the first and second measured values. The gas bubble, if present, is in at least partial contact with the sensitive region of the amperometric sensor.
