- The TGA/VMI reactor is a custom modified thermogravimetric analyzer
(Perkin-Elmer TGS-2). It was modified to provide high magnification
images of the reacting samples in the TGA pan.
- The video microscopy capabilities of the TGA/VMI have been effective
in ignition detection and characterization. The set-up has allowed us
to visualize light emissions from igniting individual particles during
runs with multiple particle samples. In addition, images of igniting
particles can provide information on the ignition mechanism.
- Combination of the video microscopy capabilities of the TGA/VMI with
the reactivity data obtained through weight loss measurements optimizes
the detection of particle ignitions.
