Study Notes
Spectrometry Principles
- Spectrometry relies on the property of colored solutions called absorptivity to measure the concentration of a substance.
Beer's Law
- Beer's Law is used in spectrometry to relate the concentration of a substance to the amount of light absorbed.
Spectrophotometer Components
- The entrance slit of a spectrophotometer is responsible for controlling the amount of light that enters the instrument.
Light Source
- A deuterium lamp is typically used as the light source for the UV spectrum in a spectrophotometer.
Beer's Law Relationships
- According to Beer's Law, the amount of light absorbed is directly proportional to the concentration of the substance.
