Sample Requirements
- µL - 3 mL for liquids
- 1 cm x 1 cm or larger for thin films
Summary of Technique
Exposure to desired discrete wavelength(s) tests the sample’s ability to absorb/transmit light. This technique can be used to determine the band gap of a material.
Information Provided & Detection Limits
Typically ppm range.
