SysMoG - Probe for Deep Aquifer On-Line Monitoring

The measuring system consists of a borehole probe with a chamber into which the dissolved gases from the surrounding groundwater diffuse. The probe is connected to the measuring module on the surface via two pipes and a circulation module. Various analysers, such as Raman or FTIR spectrometers, are used to detect the gases. The measuring module integrated into the circuit continuously detects the components of the gas mixture and records the concentration development of the individual gases over time. The borehole probe can be installed in an open borehole, e.g. with a logging winch. Alternatively, it can also be integrated into a measuring interval of a multi-packer system. The adjacent figure schematically shows the SysMoG® system for continuous measurements.
