Analytical system and method with combined differential scanning calorimetry (DSC) and raman spectroscopy

A combination DSC testing and Raman spectroscopy system (100) is provided for running investigations on a single sample (5) in the same experiment. A DSC instrument (120) includes a set of optics (150), which allows an associated Raman unit (130) to emit a pulsed laser (132) that intermittently directs a laser signal to the sample (5) and to collect the Raman signal while simultaneously running a DSC experiment on the same sample (5). The DSC has a vessel adapted to contain the sample, a thermal analysis environment is adapted to hold the vessel. An associated temperature control apparatus (160) changes the temperature of the analysis environment between temperature endpoints to observe the sample at various transitions. The Raman spectroscopy unit (130) is configured to generate laser pulses which stimulate emission of Raman spectra to provide further information about the sample without introducing excessive noise in the DSC aspect of the investigation.
