KK: /spɛktrəˈmɛtrɪk/
Relating to the measurement of light or other radiation using a device called a spectrometer.
The spectrometric analysis revealed the composition of the unknown substance.
Spectrometric → It is formed from "spectrum" (from Latin *spectrum*, meaning appearance or image) and "-metric" (from Greek *metron*, meaning measure). The word "spectrometric" refers to the measurement of spectra or the analysis of light and other electromagnetic radiation.
Think of 'spectrum' as the 'appearance' of light and '-metric' as 'measuring' it — that's how spectrometric relates to measuring different appearances of light.
