Description

Model: JSUVK6000

Ultraviolet-visible (UV-VIS) spectrophotometry is a technique used to measure light absorbance across the ultraviolet and visible ranges of the electromagnetic spectrum. When incident light strikes matter it can either be absorbed, reflected, or transmitted. The absorbance of radiation in the UV-VIS range causes atomic excitation, which refers to the transition of molecules from a low-energy ground state to an excited state.

Before an atom can change excitation states, it must absorb sufficient levels of radiation for electrons to move into higher molecular orbits. Shorter band gaps typically correlate to absorption of shorter wavelengths of light. The energy required for molecules to undergo these transitions, therefore, are electrochemically-specific. A UV-VIS spectrophotometer can use this principle to quantify the analytes in a sample based on their absorption characteristics.
