Gem Professor

WEC ProTT-EZ Raman is a dual-wavelength Raman instrument that combines NIR and Visible excitation lasers in one portable package, which is suitable for laboratory and field analysis, and can be applied to various types of the detected specimens. It features the best performance in measuring probe, which can acquire both Raman signals and florescence signals with the excellent signal-to-noise rate in a limited time, and can be used for database searching and analyzing.
