    Abstract: In order to improve a one-way measuring element, which may be inserted into an analyzer for analyzing gaseous or liquid samples and which comprises a measuring channel with a measuring zone and one or more sensors located therein, the proposal is put forward that the one-way measuring element be provided with a sensor part whose measuring channel has seals on both ends, and with a sample-taking part, and that a coupling element be placed at the inlet end of the measuring channel for direct coupling of the sample-taking part containing the gaseous or liquid sample, and that the measuring channel be filled with a calibrating and storage medium prior to the measuring process, and that the calibrating and storage medium contained in the measuring channel be displaced by the sample flowing in after the sample-taking part has been coupled to the sensor part. The one-way measuring elements obtained in this way are characterized by great simplicity of design and ease of handling.

    Abstract: A method for determining the 14C content of a gas mixture in which 14C isotopes are present as molecule constituents, is provided. The gas mixture is provided in a measuring space, wherein infrared laser radiation is supplied to the measuring space as measurement radiation. The laser radiation to be supplied to the measuring space is deflected such that it passes through the measuring space a plurality of times by interacting with the gas mixture, wherein the laser radiation is supplied to a detector, in order to determine the absorption of laser radiation by the gas mixture and therefrom determine the 14C content. For generating the laser radiation a pulsed laser is used, which as measurement radiation emits laser pulses with a pulse duration of less than 5 μs, which are supplied to the measuring space.
