1. A sample analysis system, comprising:
a control device;
a rail device for carrying cuvettes under control of the control device;
at least one independent sample distribution node arranged on the rail device for distributing samples to the cuvettes, the independent sample distribution node being used for sample aspiration, transfer, and discharge; and
at least two independent reagent distribution and measurement nodes arranged on the rail device for distributing test reagents to the cuvettes and measuring mixture liquid in the cuvettes, the independent reagent distribution and measurement nodes being used for reagent aspiration, transfer, and discharge and reagent-sample mixture liquid measurement;
the cuvettes being used for containing the samples and reagents and signal measurement;
wherein the sample distribution node comprises:
a sample distribution control device;
a sample distribution device for aspiration, transfer, and discharge of a sample to a cuvette in a current node under control of the sample distribution control device; and
a sample distribution node fixing frame for fixing various portions of the sample distribution node to an independent structure.
