    Abstract: A circuit for determining characteristics of a fluid under-test is provided. The circuit includes analog-to-digital processing circuitry for interfacing with a sensor and host electronics. The analog-to-digital processing circuitry includes a frequency generator for providing stimulus to the sensor and receiving a response signal from the sensor. Conditioning circuitry for reducing analog signal offsets in the response signal and signal detection circuitry for identifying amplitude data of the response signal are provided. Further provided is analog-to-digital conversion circuitry for converting the detected amplitude data into digital form. Memory for holding calibration data and approximated fluid characteristics of the fluid under-test is included in the circuitry. The digital form of the response signal is processed in conjunction with the calibration data and approximated fluid characteristics to generate fluid characteristics of the actual fluid under-test.

    Abstract: A hydrodynamic injector for substantially concurrently loading fluid samples to be analyzed into multiple capillary tubes of a capillary electrophoresis system. The injector includes an enclosure defining a pressure chamber for holding multiple receptacles, each containing a fluid sample, and apertures in the enclosure for passing capillary tubes into a position inside the pressure chamber and in fluid communication with the samples in respective receptacles. Electrodes on the enclosure extend into the pressure chamber for reception in the receptacles. The pressure chamber is pressurized with gas to substantially concurrently force the fluid samples from respective receptacles into the capillary tubes in preparation for a capillary electrophoresis operation.
