text: There are some common types of spectrophotometers include:
  UV-vis spectrophotometer: Measures light absorption in UV and visible ranges (200-800 nm). Used for quantification of many inorganic and organic compounds.
  1. Infrared spectrophotometer: Measures infrared light absorption, allowing identification of chemical bonds and functional groups.
  2. Atomic absorption spectrophotometer (AAS): Uses absorption of light by vaporized analyte atoms to determine concentrations of metals and metalloids.
  3. Fluorescence spectrophotometer: Measures intensity of fluorescent light emitted from samples after excitation. Allows highly sensitive analysis of samples with native or induced fluorescence.
  4. Colorimeter: Simple spectrophotometers used to measure light absorption for colorimetric assays and tests.
