• Descrição: A conversion and kit for a dual beam spectrophotometer permitting it to operate in dual wavelength mode and thereby obtaining resolution heretofore unavailable from similar machines. The present invention provides for a second light source and directs it through the sample. By eliminating the reference path of the dual beam machine, the second light source permits the converted dual beam spectrophotometer to work in dual wavelength mode and thereby generate higher resolution while using the same instrument. The conversion allows the spectrophotometer to be operated in dual beam mode and for the easy/rapid changing between dual beam and dual wavelength modes.
