Definition

Noun: - A scientific technique: Spectrographic analysis refers to the process of using spectroscopes to examine and interpret spectra. This method involves separating light or other radiation into its component wavelengths (creating a spectrum) to study the composition, structure, or properties of a material.

Usage

• Spectrographic analysis is a precise method for identifying chemical elements.
• Researchers employed spectrographic analysis to determine the mineral content of the meteorite.
• The authenticity of the painting was verified through spectrographic analysis of the pigments.

Advanced Usage

• "to perform spectrographic analysis": to carry out this specific analytical procedure.
  • The lab will perform spectrographic analysis on the sample to detect any contaminants.
• "subject to spectrographic analysis": to have a material undergo this process.
  • The unknown substance was subjected to spectrographic analysis.

Variants and Related Words

• Spectrograph (n): An instrument used for recording spectra, often employed in spectrographic analysis.
  • The observatory's spectrograph captured detailed data from the star.
• Spectroscopic (adj): Relating to spectroscopy or the use of a spectroscope.
  • The spectroscopic data confirmed the presence of water molecules.
• Spectroscopy (n): The broader scientific field of studying spectra, of which spectrographic analysis is a part.
  • Mass spectrometry is a different technique from optical spectroscopy.

Synonyms

• Spectroscopy: The general science of investigating spectra.
• Spectral analysis: Analysis based on the examination of spectra.
