Origin
China

Each atom has its own energy-level structure and absorbs or emits specific spectral lines during transitions. Measuring these characteristic lines identifies chemical composition and relative abundance, a method called spectroscopic analysis. This experimental kit uses a cooled tungsten-halogen source as the reference and a miniature spectrometer as the detector. Adding a transmission module to the source allows measurement of liquid absorbance and calculation of solution concentration, or transmittance measurements of transparent materials such as filters. Adding a reflection module allows measurement of surface-reflection spectra and calculation of material color parameters.
