Patent ID: 7665889

Claim:
A system for producing quantitative highly localized calorimetry data on a sample surface, comprising; a restively heated probe, a power source for the resistive heater on the probe, wherein both the power to the probe is variable and the resistance of the probe heater is monitored, a programmable control system adapted to position the probe, control the power source, and monitor the probe resistance; and, a program application, running on the programmable controller, adapted to; perform a baseline temperature/power measurement for the probe in a clean condition away from the surface, nano-sample the surface at a selected location either using a temperature program on the probe or by picking up a particle which adheres to the probe upon contact, determine the mass of the adhered sample; and perform a temperature/power measurement for the probe with adhered sample away from the surface, and subtract the baseline data from the sample data.
