20140374601 | Method and Apparatus for the Application of Force to a Sample for Detection Using an Electromechanical Means - The embodiments of the present invention are directed to applying intimate contact pressures to samples while undergoing ATR infrared interrogation. As a general mode of operation, after a solid sample is placed on the ATR element, a force actuator moves an anvil arm to apply a contact force to the sample against the ATR. Thereafter, when the scan is over, the user can see the result of the one or more scans. The force actuator may be a motor or a solenoid or other type of force actuator. The applied contact force may be a fixed force or may be a user-selectable force or may be automatically controlled through feedback from the spectrometer based on the spectroscopic signature of the sample material. | 12-25-2014 |
