Introduction to Capillary Electrophoresis - The DU spectrophotometer or Beckman DU, introduced in 1941, was the first commercially viable scientific instrument for measuring the amount of ultraviolet lht absorbed by a substance. Motic flow can be quite robust, with a linear velocity around 2 mm/s at pH 9 in 20 mM borate. Adenosine-5'α-32Ρtriphosphate 200 mM borate, pH 8.1.
IOP007.14A INSTRUMENT OPERATING PROCEDURE This model of spectrophotometer enabled scientists to easily examine and identify a given substance based on its absorption spectrum, the pattern of lht absorbed at different wavelengths. Beckman's National cal Laboratories (later Beckman Instruments) developed three in-house prototype models (A, B, C) and one limited distribution model (D) before moving to full commercial production with the DU.
