spectrophotometer Insights

What is spectrophotometer?

A spectrophotometer is an instrument that measures the absorbance and transmittance of light through a liquid sample. It is commonly used in chemistry, biochemistry, and material science for quantitative analysis, to determine the concentration of substances in solution by measuring the intensity of light that passes through the sample and comparing it to a reference beam. It can also be used to identify different substances based on their unique spectral fingerprints.

What other technologies are related to spectrophotometer?

spectrophotometer Competitor Technologies

flow cytometer

Flow cytometry also provides quantitative data on cell populations, but uses fluorescence and light scattering to analyze individual cells, offering alternative methods to spectrophotometry in some applications.

colorimeter

A colorimeter measures absorbance or transmission of specific wavelengths of light, similar to a spectrophotometer, but typically less precise and versatile. It serves the same purpose but with less advanced tech.

plate reader

Plate readers often incorporate spectrophotometry to measure absorbance in microplates, so they compete directly. They may also measure fluorescence or luminescence.

turbidimeter

A turbidimeter measures the turbidity of a solution, which is related to absorbance. While spectrophotometers can measure absorbance, a turbidimeter focuses solely on turbidity and can sometimes provide a quicker measurement. Both are related to spectrophotometry so it is a competitor.

Densitometer

A densitometer measures the optical density (degree of darkness) of a material. In a gel, this provides relative quantitation, similar to using a spectrophotometer.
