With the ability to measure light absorption and intensity across different spectrums, our spectrophotometers provide precise data essential for determining solution concentrations or conducting qualitative material analyses.

What is a spectrophotometer?

A spectrophotometer is a sophisticated instrument used to measure the amount of light absorbed or transmitted by a substance. It operates by passing light of specific wavelengths through a sample and measuring the intensity of light that reaches a detector on the other side. This method, known as spectrophotometry, is particularly valuable for identifying the concentration of chemicals in a solution. Hanna Instruments offers a wide array of spectrophotometers tailored to various applications, ensuring you find the perfect tool to meet your project’s requirements.

How does a spectrophotometer work?

The operation of a spectrophotometer involves generating light, which is then directed through a prism or grating to separate it into distinct wavelengths. These wavelengths are focused onto the sample, where certain wavelengths are absorbed based on the sample's properties, while others pass through or are reflected. A detector measures the intensity of the transmitted or reflected light, providing data that can be used to calculate the sample's absorption or transmission rates. This precise process is key to obtaining accurate and repeatable results in analytical applications.

Applications across industries

Spectrophotometers are indispensable tools in numerous fields, from pharmaceutical research and environmental monitoring to food production and educational experiments. In pharmaceutical laboratories, they are used to analyze active ingredients and ensure product consistency. Environmental scientists rely on spectrophotometers to monitor water quality by detecting contaminants and chemical levels. In the food and beverage industry, these instruments measure parameters like sugar content and color intensity, ensuring product quality and compliance with standards.

The evolution of spectrophotometry

The history of spectrophotometry dates back to the early 19th century, with foundational discoveries such as the observation of dark lines in the solar spectrum by William Hyde Wollaston and later studies by Joseph von Fraunhofer. These findings paved the way for spectral analysis, enabling scientists to use light spectra to examine the properties of chemical substances. The field advanced significantly in the 20th century with the development of the first commercial spectrophotometer by Beckman Instruments, revolutionizing scientific research and industrial applications. Today, spectrophotometry continues to evolve, offering greater precision, flexibility and usability.
