The DU spectrophotometer or Beckman DU, in … The DU spectrophotometer or Beckman DU, introduced in 1941, was the first commercially viable scientific instrument for measuring the amount of ultraviolet light absorbed by a substance. This model of spectrophotometer enabled scientists to easily examine and identify a given substance based on its absorption spectrum, the pattern of light absorbed at different wavelengths. Arnold O. Beckman's National Technical 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. Approximately 30,000 DU spectrophotometers were manufactured and sold between 1941 and 1976. Sometimes referred to as a UV–Vis spectrophotometer because it measured both the ultraviolet (UV) and visible spectra, the DU spectrophotometer is credited as being a truly revolutionary technology. It yielded more accurate results than previous methods for determining the chemical composition of a complex substance, and substantially reduced the time needed for an accurate analysis from weeks or hours to minutes. The Beckman DU was essential to several critical secret research projects during World War II, including the development of penicillin and synthetic rubber.opment of penicillin and synthetic rubber.
, El espectrofotómetro DU o DU Beckman fue e … El espectrofotómetro DU o DU Beckman fue el primer instrumento científico que estuvo comercialmente disponible para medir la cantidad de luz absorbida por una sustancia. Este modelo de espectrofotómetro permitió a los científicos examinar e identificar fácilmente sustancias específicas basados en su espectro de absorción, el patrón de luz absorbida a diferentes longitudes de onda. Los Laboratorios Técnicos nacionales (después Beckman Instrumentos) desarrollaron tres modelos de prototipos hechos en casa (A, B y C) y un modelo de distribución limitada (D) antes de empezar con la producción total del DU, el cual fue introducido en 1941. Aproximadamente 30,000 espectrofotómetros DU se produjeron y vendieron entre 1941 y 1976. Midiendo ambos el espectro visible y ultravioleta, el modelo de espectrofotómetro DU produjo resultados más precisos, y redujo sustancialmente el tiempo necesario para determinar precisamente la composición química de una sustancia compleja de semanas a horas o minutos.El espectrofotómetro DU Beckman Ultravioleta-Visible (UV-Vis) fue esencial para la investigación de diversos proyectos secretos durante la Segunda Guerra mundial. Schmidt otorga crédito a este diciendo que "proporcionó un adelanto en la espectroscopia óptica". Ha sido identificado como uno de los "instrumentos más esenciales" de la ciencia de la posguerra, y "probablemente el instrumento más importante que se ha desarrollado para el avance de la biociencia".rollado para el avance de la biociencia".
