This
paper describes a new analytical instrument that combines
a precisely temperature-controlled hot-stage with digital microscopy
and Direct Analysis in Real Time–mass spectrometry (DART–MS)
detection. The novelty of the instrument lies in its ability to monitor
processes as a function of temperature through the simultaneous recording
of images, quantitative color changes, and mass spectra. The capability
of the instrument was demonstrated through successful application
to four very varied systems including profiling an organic reaction,
decomposition of silicone polymers, and the desorption of rhodamine
B from an alumina surface. The multidimensional, real-time analytical
data provided by this instrument allow for a much greater insight
into thermal processes than could be achieved previously.
