History of Wells Fargo. This article outlines the history of Wells Fargo & Company from its origins to its merger with Norwest Corporation and beyond. The new company chose to retain the name of Wells Fargo and so this article also includes the history after the merger.
Other method takes advantage of the varying conductivities of blood at. different concentrations of blood. In Hemoglobincyanide method hemoglobin is chemically converted to form a cyanmethemoglobin. which is having maximum absorption around 540nm wavelength. The hemoglobin concentration is determined.
both are based on lysing red blood cells to release hemoglobin and then measuring the absorbance of the resulting solution photometrically. the resulting absorbance is proportional to the amount of hemoglobin present in the sample.est Answer: Apparently some people don't know the difference between methemoglobin and hemoglobin. As far as I know, the primary instrument is a needle and then a red blood cell count. The amount of hemoglobin can be tested by measuring oxygen saturation using electromagnetic waves.
