WebThe normal absorption spectrum of oxyhemoglobin has very little optical density above 600 nm. However, if certain poorly defined hemoglobin denaturation products are present in a hemolysate, there is a broad elevation of the absorption curve in the range of 600 nm to 620 nm. This "sulfhemoglobin" plateau is not affected by treatment with cyanide. WebAbsorbance of the diluted sample at 540 nm is compared with absorbance at the same wavelength of a standard HiCN solution whose equivalent hemoglobin concentration is known. Most hemoglobin derivatives (oxyhemoglobin, methemoglobin and carboxyhemoglobin, but not sulfhemoglobin) are converted to HiCN and therefore …
