Title:
APPARATUS AND METHOD FOR SIMULTANEOUS MEASUREMENT OF MASS AND HEAT FLOW CHANGES
Document Type and Number:
WIPO Patent Application WO1999028735
Kind Code:
A8
Abstract:
Provided is a mass and heat flow measurement apparatus comprising sample and reference microresonators (70, 80), such as sample and reference quartz crystal microbalances; sample and reference heat flow sensors (75, 85), such as sample and reference isothermal heat conduction calorimeters; and sample and reference heat sinks coupled thermally to the heat flow sensors. The apparatus may be used to measure changes in mass due to sample (8) on a surface of the sample microresonator and also to measure heat flows from the sample (8) on the surface of the sample microresonator by utilizing the heat flow sensors, which are coupled thermally to the corresponding sample or reference microresonators. Also provided is a method for measuring the mass of a sample (8) and the flow of heat from the sample (8) to the heat sink by utilizing such apparatus.
