Construction and Working of Double Beam Spectrophotometer

The measurement of the transmittance or reflectance of analytes in a sample is often done using a twin beam spectrophotometer. Here, samples consist of solvent-like vapours or clear or opaque solids, such as polished glass. Numerous biochemical kinds exhibit color, which causes them to absorb ultraviolet or visible light. By using colorimetric techniques within the spectrophotometer, the transmitted light may be measured.

Correction of absorbance for solvent
blank
In a single beam setup, there could be
differences in the light energy between
ratio recording samples.
Corrections for stray light, fluctuating
beam strength, and electronic noise are
made in real-time.

4. Uses
UV Spectrometers are employed in many different
branches of study, including chemistry, molecular biology,
physics, and the material sciences. These tools are
employed in the semiconductor, optical manufacturing,
laser, printing, forensic examinations, and laboratory
research sectors. The machinery used in spectroscopic
analysis quantifies a wide range of analytes, including
chemical compounds and biological macromolecules. The
bulk of spectroscopic research involves solutions.
However, it is also possible to study chemicals in their
solid and gaseous forms.

The light beams produced by reflection are helped to travel by the
double beam spectrophotometer. A single-beam spectrophotometer can
be used in the same way as a double-beam spectrophotometer. The
biological specimens are illuminated by the light source, and the findings
are then digitally recorded using a computer system.
