Sampling device and sampling method

A sampling system, comprising

• the sampling device of any of the preceding claims,
• a sensor connection for connecting a sensor for detecting an analyte in a transporting medium,
• an infeed line, in fluid communication with the infeed-line passage of the sampling device,
• an outfeed line, in fluid communication with the outfeed-line passage of the sampling device and with the sensor connection,
• a first pump to transport a medium through the outfeed line to the sensor connection and, as an option,
• a sampling line and, connected thereto, a second pump for pumping a sample into the sample chamber.

A sampling system comprising

• a hollow needle,
• a sampling device having an analyte receiving chamber in fluid communication between an infeed line and an outfeed line, the analyte receiving chamber having an opening that is closed off by a membrane permeable to analyte to allow the analyte to pass through from a region outside the analyte receiving chamber into the analyte receiving chamber, and the analyte receiving chamber being arranged in the hollow needle to form a sample chamber,
• a sensor connection,
• a first pumping device to transport a transporting. medium or calibrating medium or flushing medium through the analyte receiving chamber to a sensor connection,
• a second pumping device to draw in by suction and, as an option, to expel a medium intended for analysis through the hollow needle, and
• a control system in operative connection with the first pumping device, the control system being arranged to cause the transporting medium to be pumped through the sampling device at a preselected time to allow a sample of the transporting medium possibly containing analyte to be obtained.
