• Resumen

  • The majority of freshman chemistry laboratory programs include experiments that employ visible spectroscopy to teach Beer's law and derive related concentration information. These experiments are often done with a Baush and Lomb Spectronic 20 or Spectronic 21. While these experiments and equipment are "status quo" at most institutions, they do have a number of limitations. We have developed an alternative instrument and software that offers significant advantages over the above spectrometers.
