The holding mechanism is usable with sediment core devices using replaceable acrylic tubes, which do not have steel-tubed liner housings. The patented product and the respective process connect the pipe firmly and tightly to the holder. The proposed combination of holder and seal results in a simple handling and reduces the susceptibility to errors of sediment core devices.

The monitoring system for predicting process disturbances in biogas plants is based on three patented early warning indicators. These are suitable for the early identification of process disturbances in biogas plants (agricultural, sewage sludge and/or lipid-containing waste) and if necessary Wastewater treatment plants.

The automated sampler enables autonomous, robust sampling. It can be used in the field for several years to obtain and store water samples for environmental analysis (including isotope analysis). Sample storage takes place without atmospheric exchange and enables the following analyses: environmental monitoring, water analysis, isotope analysis, tracer analysis.
