Estimating the term…
A gas-measuring chip (10), used with a gas-measuring device (100) of a portable chip measurement system, has a carrier (11) and measuring channels (20, 20′, 20″). A regenerable, nonconsumable sensor (30, 30′, 30″) is arranged in each measuring channel. A method includes inserting the gas-measuring chip (10) into the gas-measuring device (100) and connecting one measuring channel of the gas-measuring chip (10) to a pumping system (120, 121) of the gas-measuring device (100). A measurement is carried out with a first measuring channel (20, 20′, 20′) with a switching over to a measuring channel different from the first measuring channel. The sensors (30, 30′, 30″) of the measuring channel used last is regenerated and optionally simultaneously there is a measurement with the measuring channel switched over to. There is a switching over to a measuring channel, which is different from the measuring channel last used for the measurement.
A gas-measuring chip for use with a gas-measuring device of a portable chip measurement system, the gas-measuring chip comprising:
A gas-measuring chip in accordance with claim 10, wherein all sensors of one measuring channel are based on the same principle of measurement.
A portable chip measurement system comprising:
A method for operating a portable chip measurement system comprising a gas-measuring chip, a portable gas-measuring device, wherein the gas-measuring device has a receptacle, into which the gas-measuring chip is insertable, at least one pumping system;
