The utilisation of spectrophotometers in science applications led to the development of more complicated analyzers, thus bringing them to the forefront of analytical instruments. Single-beam spectrophotometers are the most frequently used and simplest of these critical instruments. Biochemistry, clinical and medical laboratory science, pharmaceutical laboratories, and even paper and ink makers use these versatile machines.
These UV Spectrophotometer products are composed of about six components: Light source, collimator or light beam intensifier, monochromator or beam purifier/splitter, sample bay or holding cell, photograph detector or photodiode/photomultiplier, and logical instrument, generally a computer system with suitable software to make sense of the result.
The source of illumination transmits thru a collimator consisting of a lens focuser. This intensifies the beam for the monochromator, as some of the light energy may be lost during beam splitting. The beam then travels inside the monochromator, which as its name implies, splits the beam into a single-wavelength light beam. This gets transmitted through the sample.
The sample is mostly a liquid that's emulsified in a diluent that creates a reaction with it to bring out the chemical make-up. The light beam travels thru this matrix, and the ensuing absorption of light is measured by the photomultiplier or photodiode. The photodiode is a device which is sensitive to specific light wavelengths, and concerts this to electric impulses. The photomultiplier has a similar function, but can increase the electric signal for research.
This electrical signal is sent to the analytic machine, which compares the assimilation of light with a huge database, therefore giving a reading on a PC screen or a paper printout. The single beam spectrophotometer uses a clean beam to compare with a cuvette, standard or blanking. This is obligatory for not only the pureness of the light, but to set the machine for read outs.
Single-beam spectrophotometers have been utilized since the late 1960's, and have advanced to systems that take up only minimum lab bench space. Their speed and reliability has made them the gold standard for many laboratory functions. Many disciplines use these machines, and without them laboratories around the planet would not be as functional as they are today.
