Autoanalyzer

AUTOANALYZER

An auto analyzer sequentially measures blood chemistry through a series of steps of mixing, reagent reaction and colorimetric measurements.

Itconsists of

·        Sampler: Aspirates samples, standards, wash solutions into the system

·        Proportioning pump: Mixes samples with the reagents so that proper chemical color reactions can take place, which are then read by the colorimeter

·        Dialyzer: separates interfacing substances from the sample by permitting selective passage of sample components through a semi permeable membrane

·        Heating bath: Controls temperature (typically at 37 °C), as temp is critical in color development

·        Colorimeter: monitors the changes in optical density of the fluid stream flowing through a tubular flow cell. Color intensities proportional to the substance concentrations are converted to equivalent electrical voltages.

·        Recorder: Displays the output information in a graphical form.
