Bruker's MultiRAM is a stand-alone high-performance Fourier transform Raman spectrometer. When sample fluorescence is a problem, FT-Raman analysis with near-infrared excitation at 1064nm is the only solution. As sample fluorescence can be orders of magnitude more intense than Raman scattering, the presence of fluorescence often precludes observation of Raman scattering. The MultiRAM has a large sample compartment to utilise an extensive range of pre-aligned sampling accessories featuring Bruker ́s automatic accessory recognition. The new Raman video stage makes Raman analysis a breeze. The MultiRAM can accommodate a second laser and detection system for use with 785nm.
