Abstract: Disclosed are systems and methods for detecting a malfunction in an automated analyzer. The systems and methods may include receiving a signal from a sensor (116), such as a Hall effect sensor located proximate a coil (104) of a solenoid valve (100). The signal from the sensor may be correlated to a magnetic flux or change in the magnetic flux generated as a plunger (102) of the solenoid valve is drawn into the coil when the coil is energized. Deviations in the signal from a reference may indicated a malfunction of the solenoid valve. Upon detecting a malfunction, a pre-failure status may be determined.

Abstract: A chemistry analysis machine and method for using the machine include adding heating functionality to provide faster test specimen heating times or comparable specimen heating times while using containers or cuvettes made of materials such as plastic that have lower thermal conductivity. In one example, a mixing bar is heated prior to contacting the test specimen within the container to provide the additional heating capability to the system. In one example where the mixing bar is heated, a heater is added to the system to heat the rinse water used to rinse the mixing bar after it is washed and prior to its next use in contacting a test specimen.
