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.
Hemoglobin is usually measured as a part of the routine complete blood count (CBC) test from a blood sample. Several methods exist for measuring hemoglobin, most of which are done currently by automated machines designed to perform different tests on blood. Within the machine, the red blood cells are broken down to get the hemoglobin into a solution. The free hemoglobin is exposed to a chemical containing cyanide that binds tightly with the hemoglobin molecule to form cyanomethemoglobin. By shining a light through the solution and measuring how much light is absorbed (specifically at a wavelength of 540 nanometers), the amount of hemoglobin can be determined.
