An anaerobic chamber allows the investigation of reactive matter transport in laboratory scale also for anoxic or anaerobic environmental conditions. The chamber is operated with nitrogen or forming gas. The oxygen concentration can be regulated between 0 - 20%. For reaching oxygen concentrations below 0.5% a catalytic converter has to be instrumented and the chamber is operated with forming gas. A detachable front panel allows for the instrumentation with big experimental setups.

The groundwater monitoring is used to evaluate the local quality and quantity of the groundwater. These information are required to obtain important insights in the hydrochemical processes in the aquifer, as well as the origin and residence time of groundwater.
The Grundfos MP 1 submersible pump set with a connected, closed flow cell enables observations of the physicochemical parameters with digital IDS sensors (temperature, pH, electrical conductivity, redox potential, dissolved oxygen), …

Our instrument is used for the quantitative measurement of ion concentrations by detecting the electrical conductivity. By default, the system is operated to determine anion contents. For most of the measured ions the determination limit is below 1 mg/L. A modification of the device, i.e. replacement of the separation column and change of the eluent, allows also for the detection of cations.

An instrument (Elementar varioTOCselect) for measuring different carbon fractions (TOC, NPOC, TC, TIC) can be used for the analysis of both liquid and solid samples. The determination limit of the system is 1 ppm.
