The present disclosure is directed toward a measurement system capable of rapid spectroscopic and calorimetric analysis of the chemical makeup of a test sample. Systems in accordance with the present disclosure include a low-thermal-mass sample holder having a substrate whose surface has been engineered to create a large-area sample-collection surface. The sample holder includes an integrated temperature controller that can rapidly heat or cool the test sample. As a result, the sample holder enables differential scanning calorimetry Fourier-Transform Infrared Spectroscopy (DSC-FTIR) that can be performed in minutes rather than hours, as required in the prior art.
