Spectrophotometers
The spectrophotometer, invented in 1940 by Arnold J. Beckman and collaborators, was the Beckman company's greatest discovery. Before this, the chemical analysis was cumbersome and late. At first the technology of the equipment was experimental, which led to constant redesign, along the way the hydrogen lamp was invented, which offered improvements.
Over time it was automated and the speed of response improved, gradually incorporating control and detection systems that have resulted in the current spectrophotometer.
Types of laboratory spectrophotometers a Laboratory may need
Portable Benchtop Spectrophotometer
The importance of color as a physical characteristic and quality in food have a relevant role related to food additives. Consumers prefer attractive-looking products, and color is the first thing they evaluate. Usually, dyes are used to highlight the natural color of foods or to return the color lost in chemical processes carried out for their preservation. However, color in foods is not just an aesthetic attribute.
The dyes can be of natural or synthetic origin, legally they are considered an additive. These substances belong to the group of additives that present the greatest differences in the legislation of the countries. Its use could generate situations that harm the health of the consumer, since the product may not be as expected, or in the worst case be toxic. In general, in the legal regulations of each country there are different requirements on the type of dye, the concentration and the declaration of the ingredient in the labeling, it is also mandatory to characterize the food by the permisology associated with marketing.
Portable Spectrophotometer
Spectrophotometry is an analytical technique that allows determining the concentration of a compound in solution. It is based on the principle that molecules absorb electromagnetic radiation and in turn that the amount of light absorbed depends linearly on the concentration. A spectrophotometer is used to measure the amount of light absorbed by a solution.
That is, spectrophotometry refers to the measurement of relative amounts of light absorbed by a sample, as a function of wavelength. It is characterized by its accuracy, sensitivity and its applicability to molecules of different nature (pollutants, biomolecules, among others) and aggregation state (solid, liquid, gas).

Spectrophotometers operating
The spectrophotometer is an optical analysis instrument that allows projecting a beam of light through a sample and thus determining, identifying, and quantifying the absorbance or transmittance of energy. The amount of light absorbed or transmitted is proportional to the concentration of the material.
This difference is specific to certain species, so the equipment yields absorption spectra that are unique to each substance and are often used as a fingerprint. Spectrophotometric methods vary depending on the range of the working spectrum, they can be visible spectrum, UV and infrared.
