A spectrometer is an essential scientific instrument for non-destructively analyzing a substance's composition, structure, or concentration. It works by separating and measuring how a sample interacts with energy—such as light—producing a unique "spectrum" that acts like a chemical fingerprint. Common types include optical, mass, and NMR spectrometers, each targeting different properties.
A miniature spectrometer works by precisely breaking down light into its component wavelengths to analyze material properties. Light enters through a slit, is collimated into a parallel beam, and then dispersed by a diffraction grating.
Here's a step-by-step explanation of how it works:
A spectrometer separates and measures light intensities across wavelengths, producing a spectrum. It identifies materials and studies properties.
A spectrophotometer incorporates a spectrometer but adds a built-in light source to measure how much light a sample absorbs or transmits at specific wavelengths. It is primarily used for quantitative concentration analysis.
A spectrometer identifies the composition of a substance,
while a spectrophotometer quantifies the concentration of a substance.
