Patent ID: 8354015

Claim:
A method for detecting the presence or absence of a gas bubble in a liquid to be measured, where the gas bubble, if present, is in at least partial contact with a sensitive region of a sensor in a measuring chamber, the sensor for determining the concentration of a gaseous component dissolved in the liquid, the method comprising: setting a gas partial pressure, which differs from an expected value of the gas partial pressure of the gaseous component in the liquid to be measured, at the sensor using a select one of: an aqueous liquid, a gas, and a mixture of gases containing the gaseous component to be determined in suitable concentration; exposing the sensor to the liquid to be measured; waiting until the liquid to be measured attains standstill; recording a signal from the sensor as a function of time until the signal becomes constant; and inferring the presence or absence of a gas bubble from a variation of the signal over time.
