    摘要: An analyte is separated from a fluid sample by introducing the sample into a cartridge having a sample port and a first flow path extending from the sample port. The first flow path includes an extraction chamber containing a solid support for capturing the analyte from the sample. The cartridge has a second flow path for eluting the captured analyte from the extraction chamber, the second flow diverging from the first flow path after passing through the extraction chamber. The sample is forced to flow through the extraction chamber and into a waste chamber, thereby capturing the analyte with the solid support as the sample flows through the extraction chamber. The captured analyte is then eluted from the extraction chamber by forcing an elution fluid to flow through the extraction chamber and along the second flow path.

    摘要: A system for controlling the temperature of a reaction mixture comprises at least one heating device for heating the mixture and a power regulator for regulating the amount of power supplied to the heating device. A controller in communication with the power regulator includes program instructions for heating the reaction mixture by setting a variable target temperature that initially exceeds a desired setpoint temperature for the mixture. When the heating device reaches a threshold temperature, the variable target temperature is decreased to the desired setpoint temperature. In another embodiment, the controller includes an adaptive control program for dynamically adjusting the duration or intensity of power pulses provided to the heating device.
