What component is not needed in a chemiluminescent immunoassay analyzer?

In a chemiluminescent immunoassay analyzer, the primary components include a photodetector, which captures the light emitted during the reaction, and often a monochromator, which helps in isolating specific wavelengths of light to improve measurement accuracy. The wash station is utilized to prepare samples and maintain the overall integrity of the assay by minimizing background interference.

A source lamp is not required because chemiluminescence relies on chemical reactions that produce light without the need for an external light source. Instead of using light generated by a lamp, the assay depends on the light emitted from the biochemical reactions occurring within the sample. This is fundamental to the operation of chemiluminescent assays, as they are designed to detect the specific light produced by the reaction rather than any additional light input.
