Equations for the spectrophotometric analysis of hemoglobin mixtures.

Abstract The extinction coefficients for deoxyhemoglobin, oxyhemoglobin, and carbonmonoxyhemoglobin as well as those of ferrihemoglobin between pH 6.2 and 8.8 are given at a number of wavelengths. Equations are presented for the analysis of ternary mixtures of these hemoglobin derivatives.
