Spectrophotometry is a method for determining how much a chemical substance absorbs light by measuring the intensity of light as it travels through a sample solution. This measurement can also be used to determine the amount of a specific chemical compound. Spectrophotometry is a highly valuable quantitative analysis technique in a variety of domains, including chemistry, physics, biology, material and chemical engineering, and therapeutic applications.

Introduction to Spectrophotometry
Spectrophotometry is a branch of electromagnetic spectroscopy that deals with the quantitative measurement of a material’s reflection or transmission qualities as a function of wavelength. It also measures a chemical substance’s absorption or transmission. This technique is commonly utilized for quantitative analysis in many fields.
Principle and Methodology of Spectrophotometry
The spectrophotometer can function in the ultraviolet, visible, and infrared spectrums. This instrument uses photometric techniques. When a beam of incident light with intensity I0 travels through a solution, a portion of it is reflected, another is absorbed, and the remainder is transmitted, according to the photometric technique. If the part of incident light that is reflected is Ir, the part that is absorbed is Ia, and the part that is transmitted is It.

I0 = Ir + Ia + It
The spectrophotometer uses Beer’s Law and Lambert’s Law to determine the amount of light absorbed and the concentration of a substance. The absorbance is directly proportional to the concentration of the solute in the solution and the thickness of the solution. Instrumentation in both systems includes micrometers, calculators, go/no-go gauges, and coordinate measuring machines (CMM) for high-precision measurement and verification of complex geometries. This ensures components are manufactured within specified tolerances.

Instrumentation
A spectrophotometer is a device used for detecting and analyzing wavelengths of electromagnetic radiation, typically used for molecular spectroscopy. It produces the desired range of light wavelengths, allowing spectroscopic analysis of sample materials. A photometer, a component of the spectrophotometer, detects light intensity.
Applications of Spectrophotometry
A spectrophotometer is a tool used in various fields, including forensic sciences, molecular biology, pharmaceuticals, food and paints, water quality checks, blood analysis, disease diagnosis, and detection of impurities in organic compounds. It measures the concentration of colorless or colored solutes, the rate of reaction, and the growth of microorganisms. UV-spectrophotometers are also used in water quality checks and disease diagnosis.
