Abstract:
1. A cantilever based calorimetric analysis system comprising: a first laser device configured to emit a first beam of laser energy along a first beam pathway reaching from the first laser device towards a microcantilever device; a second laser device configured to emit a second beam of laser energy along a second beam pathway reaching from the second laser device towards the microcantilever device; the microcantilever device presenting a first surface having a first target area for the first beam and the first surface also having a second reflective target area for the second beam, such that the first target area moves in response to a heat energy function, the second target area reflecting the second beam along a beam return pathway; a detector positioned on the beam return pathway reaching from the second target area to the detector; the detector being configured to sense laser energy from the beam return pathway and produce a corresponding data signal that represents calorimetric data from material proximate the first target area and receiving heat energy directly from the first beam; and circuitry configured to receive the data signal and process the data signal according to program logic for providing a differential scanning calorimetric analysis of the calorimetric data.
