What is the role of the recorder in a spectrophotometer?

The role of the recorder in a spectrophotometer is to produce a record of the signal. This process involves capturing the intensity of light that is transmitted or absorbed by the sample over a range of wavelengths, resulting in a spectral output that can be plotted as a graph. The recorder translates the elecromagnetic signal into a readable format, allowing for analysis of how much light is absorbed or transmitted at various wavelengths. This data is critical for quantifying the concentration of substances in the sample, as it provides the necessary information to interpret the results accurately.

Other components in a spectrophotometer serve different functions, such as measuring temperature, controlling the light source, or performing chemical analysis, but the specific function of the recorder is to document and output the signal generated during the measurement process.
