Applications
Identify substances and determine concentrations
Application
Degree of hydrogenation
Monitoring the degree of hydrogenation of liquid organic hydrogen carriers
Liquid organic hydrogen carriers (LOHC) are organic substances that can be loaded and unloaded with hydrogen through a catalyzed reaction. This technology can be used to store and transport sustainable hydrogen safely, efficiently and economically. With the Optoquant Raman sensor, a solution has been developed to determine the degree of hydrogenation (degree of hydrogen loading) easily and with high accuracy. Thanks to the device's internal evaluation, the system can determine the hydrogen load as LOHC Degree of hydrogenation in real time and output it via the process interface.
Application
Ammonia sensor
Monitoring the ammonia concentration in aqueous solution
Ammonia is one of the most frequently produced basic chemicals, the starting material for the production of all other nitrogen compounds and also a critical environmental pollutant. Reliable analysis for the determination of ammonia is therefore of great importance both for industrial production and for environmental monitoring. With the Optoquant Raman sensor, ammonia dissolved in liquids can be detected and precisely quantified at concentrations < 0.5 % with a laser power of just 0.7 mW. The figure shows the calibration of the sensor to the ammonia concentration in aqueous solution based on a characteristic Raman band at 3300 cm-1. The use of the pre-calibrated system as an Ammonia sensor enables Raman-based inline measurement in product-carrying pipes without the complex and costly installation effort of an invasive measuring point.
