SPECTROPHOTOMETRIC AND NEPHELOMETRIC DETECTION UNIT

摘要

The present invention relates to a method and apparatus for analyzing a sample by providing two light sources, coupling light emitted from the two light sources into a common beam, guiding the common beam through a sample to be analyzed to generate a first signal and a second signal different from the first signal. The first signal is used to obtain a nephelometric measurement and the second signal is used to obtain a spectrophotometric measurement of the sample. The methods and apparatus are useful in in-vitro diagnosis.
