l Deep-sea research: The Presens sensor point and reading unit are integrated in a titanium alloy joint and can withstand a pressure of 600 bar, so that oxygen measurements can be carried out at a depth of 6,000 meters.
l Beer brewing industry: The oxygen probe O2 Probe OxyPro TR & TRM is integrated in the Varivent fitting for oxygen measurement in the process chain.
l Production-scale bioreactors: Oxygen Probe OIM-PST3 has developed a robust, autoclavable probe that is compatible with most ports and port adapters for monitoring oxygen in production-scale bioreactors.
l The implantable Presens miniature sensor IMP-PST7 is integrated in the catheter together with temperature and pressure sensors. This multi-sensor device was developed for brain surgery.
l Single-use bioreactors: Presens sensors for non-contact measurements are integrated in single-use bioreactors (bags). Factory calibration procedures are established for ease of use.
l Semiconductor development: We have developed an extremely robust Teflon flow cell that can withstand oxidation, corrosive chemicals (e.g. TMAH up to 25%) and material abrasion, while being able to monitor oxygen in industrial environments.
l Blood gas analyzer: Presens has developed a solution for oxygen perfusion monitoring in blood gas analyzers. After ethylene oxide sterilization, an oxygen sensor with a fast response time is integrated into a specially designed flow cell.
l Natural gas: Metal flow-through connectors with integrated Presens oxygen sensors are used to monitor oxygen content in natural gas pipelines. The challenge was to develop an extremely hermetically sealed measurement solution to detect 0Oxygen concentrations in the range of 5 to 200 ppmv.
l Transformer oil: An optical exchange window and a reading unit are integrated in the transformer to monitor the oxygen content of the transformer oil. A system with excellent long-term stability (10-year shelf life), oil-tight joints and resistance to temperatures from -40 °C to + 80 °C must be built so that it can work in desert and polar climates.
l Zero-gravity experiments: Due to their small external size, electro-optical modules (EOMs) and non-invasive sensor points are used to monitor oxygen in closed ecosystems in space. The device must be vibration-resistant to accommodate the launch and landing procedures of the satellite mission.
l Cell Assay Cell Fitness: Single-use supplies with integrated sensors and corresponding readout electronics are provided for use in high-throughput cell culture analysis systems. A wide range of culture parameters and cell suitability can be monitored.
l Fish farming: An extremely robust probe oxybase for seawater has been developed to monitor the water quality of fish farms.
l Wastewater treatment: Oxygen is an important indicator of microbial activity, and with it is the degradation of pollutants in wastewater treatment. Presens' rugged steel probes OxyBase and OxyPro can be connected directly to the control unit for monitoring the process in the treatment plant.
l Fuel cells: Presens sensor points SP-PST3, SP-PST7 and miniature sensor NTH-PST7 are used to conduct battery testing and monitor the diffusion process in fuel cell development.
l Packaging: Oxygen can affect the quality and shelf life of some products. Presens' ultra-fast oxygen sensors are used to monitor oxygen in the automatic packaging process. The all-round equipment allows for quick quality checks on filled, packaged or bottled products.
l Orbital metal welding: The oxygen incorporated during the welding process may cause corrosion. Therefore, the welded joints were flushed with argon and an oxygen measuring device from Presens was used to detect oxygen traces below 200 ppm.
l COVID-19 vaccine development: Presens single-use oxygen SP-PST3 and pH sensor dot SP-HP5 are used in single-use bioreactors to monitor culture conditions during vaccine development.
l Organ transport: Continuous perfusion can prolong the survival time of cells, tissues, and organs during transport. Presens miniaturized non-invasive sensors are used in perfusion monitoring devices during organ transport.
l Personalized medicine: Presens non-invasive sensors are integrated in dedicated single-use cell culture equipment for the development of personalized medicines.
