Abstract: An automatic sampling apparatus for taking liquid samples for the qualitative or quantitative determination of at least one analyte contained in the sample liquid includes a sample line that can be fluidically connected to the sampling station, a pump device, at least one sample container that can be fluidically connected to the sample line, and an electronic control system. The electronic control system is configured to fluidically connect the sample line to the sample container such that a fluid flow path extending from the sampling station through the sample line into the sample container is formed. The electronic control system is further configured to transport, using the pump device, a definable volume of the sample liquid, in the form of a liquid sample, along the fluid flow path into the sample container. The sampling apparatus is configured for concentrating or extracting the analyte present in the liquid sample.

Abstract: The present disclosure relates to a measuring apparatus for analyzing a measuring medium. The measuring apparatus includes a probe housing, a radiation source, and coupling and decoupling optics. The optics have a measurement window in the probe housing to direct radiation of the radiation source into a measuring region outside the probe housing and including the measuring medium, and to block measuring radiation from the measuring region. Via the optics, a receiving device detects measuring radiation and generates output data. An additional physical or chemical sensor is integrated into the probe housing and is designed to detect a measurand of the measuring medium and output measurement signals. An electronic measurement unit is configured to collect and process the output data of the receiving device and the measurement signals of the additional physical or chemical sensor.
