Method for performing spectroscopic analysis of inhomogeneous test samples

摘要

A method is provided for more accurately calculating the concentration of analytes or components in test samples. The method includes the use of an algorithm for analysis, and selection of sets of signal measurements from a spectrophotometer. Sets of signal measurements are selected to avoid inhomogeneities, i.e. air bubbles, artifacts and dilution, in test samples being analyzed. The method has application to the spectroscopic determination of the concentration of hemoglobin derivatives or fractions in a blood sample.
