Raman spectroscopy is a spectroscopic analysis method that can be used to identify substances and determine concentrations. The sample to be analyzed is irradiated with a laser. A very small proportion of the light interacts at the molecular level - the so-called Raman scattering. This light is optically separated according to “color” and detected. A Raman spectrum is obtained by plotting the measured intensities of each color.
The spectrum obtained in this way contains a fingerprint area in which substances leave their characteristic “fingerprint”. The intensity is also a measure of the respective concentration of a substance. Raman spectroscopy is therefore a powerful tool both in the laboratory and in process analysis technology (PAT). The method is suitable for gases, liquids and solids.
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.
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.
Gas analyzer
Inline analysis of gases in explosion-proof areas
In modern production, process information is a decisive market advantage for increasing efficiency. Our Optoquop Process Raman spectrometer for gases enables you to monitor the gas composition “inline” and in real time. Detect changes in the composition of the atmosphere to be analyzed or the gas flow in explosion-protected areas. The laser may shine into Zone 0 and has a temperature class T4. The spectrometer may be set up in Zone 1.
Increase the efficiency of your production processes with the Optoquop process and become more profitable and more resistant to external market influences.
