Abstract :
This paper describes a multiwavelength transmission spectrophotometry set up to study the feasibility of measuring hemoglobin derivatives in whole blood, utilizing transmission pulse oximetry. Comparison of measured relative absorbance spectra with standard extinction coefficients versus wavelength data shows that the system closely reproduces the standard spectra of blood
