摘要： A QCM sensor apparatus comprising a sensor holder (2) having a compartment for receiving a QCM sensor, the compartment having a substantially planar extension, a first temperature sensor (14a) and a second temperature sensor (14b) arranged separated from each other along a line transverse to the planar extension; and a controller (13) configured to determine a temperature difference, ΔT, between the two sensors, and operating the QCM apparatus based on this temperature difference.
By determining and monitoring not only the temperature in the measurement cell, but also the temperature difference ΔT, the controller may therefore improve measurement performance.

摘要： A quartz crystal microbalance, QCM, sensor apparatus comprising a fluid selector unit (7) for selectively placing a sample fluid container in fluid connection with a measurement cell (5) formed above a QCM sensor (1), said fluid selector unit having a plurality of inlet ports (32), a sensor outlet (33) configured to be in fluid connection with said sensor, and a valve arrangement (10) for selectively connecting one of said inlets to said outlet. The fluid selector unit (7) is sandwiched between the fluid sample containers (8) and the sample holder (2), and the sample fluid containers (8), fluid selector unit (7) and sensor holder (2) are arranged in a compartment (22) of a thermally insulating housing (21), an interior of the compartment (22) having a substantially homogeneous temperature.
The invention facilitates temperature control, such as maintaining a stable temperature and ensuring a desired temperature change.
