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.

Method for performing spectroscopic analysis of inhomogeneous test

A novel fluid sampling device has been developed. This device provides for sample entry to be handled automatically by the instrument, thus allowing the operator to be involved in other activities while the sampling process is underway. It also assures reproduceable sample size, automatically cleans the sampling device between samples, and reduces the risk of user injury. Furthermore, the sampling system allows for the use of any forseeable collection mechanism.
