A spectrometer is a device used to measure the intensity of light across a range of wavelengths, offering comprehensive spectral analysis. It's commonly employed in scientific research and analytical chemistry to identify the chemical composition of substances. On the other hand, a spectrophotometer measures the amount of light absorbed or transmitted by a sample at specific wavelengths, typically used for quantitative analysis or determining concentrations. While both instruments utilize light analysis, spectrometers provide a broader spectrum overview, whereas spectrophotometers focus on precise measurements at particular wavelengths, catering to different analytical requirements in various scientific disciplines. https://www.dnatestingexperts.com/spectrometer-vs-spectrophotometer-whats-the-difference/
