Quantitative analysis of gases
Raman spectroscopy is a powerful technique with numerous analytical applications. Our recent whitepaper ‘Quantitative laser Raman spectroscopy of gases’, looks at how Raman systems can be used to measure gas mixture compositions with high measurement precision, sensitivity and trueness. It discusses how the gem 532, finesse 532 and opus 532 can be used as the excitation source in different Raman systems using both 90ᵒ and 180ᵒ scattering configurations. Laser Quantum has also developed the ventus solo specifically for Raman Spectroscopy. It features a narrowed linewidth of 10 GHz or 0.3 cm-1, approximately the resolution limit of many CCD based Raman spectrometers. Also popular for extremely high-resolution systems is the torus actively locked single frequency laser, with a linewidth of <1 MHz. Read the full paper to see how these Raman systems can be integrated into your process control application, especially if it requires real time (automated) feedback.
