ORGANISM DETECTION APPARATUS
A detection apparatus configured for PCR testing includes a carrier structure and a temperature detection module. The carrier structure is configured to carry a test tube, and the test tube is configured for containing a reagent and a specimen. The temperature detection module is disposed on the carrier structure and includes a heat transfer medium and a temperature sensor. The heat capacity of the heat transfer medium is approximately equal to a preset value, so as to match heat capacity of the reagent. The temperature sensor is configured to sense a temperature of the heat transfer medium. In addition, a method for detecting a temperature of the detection apparatus is also provided.
Measurement of an analyte with a cartridge
A method of performing an optical measurement of an analyte in a processed biological sample using a cartridge is provided. The cartridge is operable for being spun around a rotational axis. The method comprises: placing the biological sample into a sample inlet; controlling the rotational rate of the cartridge to process a biological sample into the processed biological sample using a fluidic structure; controlling the rotational rate of the cartridge to allow the processed biological sample to flow from the measurement structure inlet to an absorbent structure via a chromatographic membrane, and performing an optical measurement of a detection zone on the chromatographic membrane with an optical instrument. An inlet air baffle reduces evaporation of the processed biological sample from the chromatographic membrane during rotation of the cartridge.
