Provided are a measurement apparatus and a measurement system comprising sample and reference microresonators, such as sample and reference quartz crystal microbalances; sample and reference heat flow sensors; and a heat sink coupled thermally to the heat flow sensors. These may be used to measure changes in one or more properties, such as mass, due to a liquid sample on a surface of a sample microresonator and also to measure heat flows from the sample 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 one or more properties, such as mass, of a liquid sample and the flow of heat from the sample to the heat sink by utilizing such apparatus.

Apparatus and method for measurement of mass and heat flow changes

Provided is a mass and heat flow measurement apparatus comprising sample and reference microresonators, such as sample and reference quartz crystal microbalances; sample and reference heat flow sensors, 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 a sample on a surface of the sample microresonator and also to measure heat flows from the sample 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 and the flow of heat from the sample to the heat sink by utilizing such apparatus.

Apparatus and method for simultaneous measurement of mass and heat flow changes

Probe (1) to be used in a microcalorimeter for various types of heat measurements. The probe having a good thermal contact with thermodetectors (5,6) used in the calorimeter. The probe is designed as a substantially cylindrical hollow body has at least one outer surface (4, 11) which is in contact with the thermodetectors. The outer surface of the probe is provided with a helix groove (2) in which a tube (3) for supplying the continuous flows is arranged in good thermal contact with the probe. The cavity (10) of the body is used for the introduction of the ampoules (9).
