Data for: A second-derivate fitting algorithm for the quantification of free hemoglobin in human plasma

This Microsoft Excel Sheet contains a Macro for the use with a standard absorption spectrophotometer. Recorded spectra can be entered into the file and are automatically evaluated with the second derivative fitting method describe in the submitted Article. Additionally, the formulas of Harboe and Kahn, which represent the current state of the art, are also implemented for comparison and easy of use.
