Near-infrared (NIR) Raman spectroscopy can damage samples, especially dark ones, due to laser heating. This study quantifies thermal risks and provides safety guidelines for analyzing various materials.

Area of Science:

  • Analytical Chemistry
  • Spectroscopy
  • Materials Science

Background:

  • Raman spectroscopy is widely used as a nondestructive analytical technique.
  • High-power near-infrared (NIR) lasers in commercial Raman instruments can cause sample damage.
  • This risk is critical for irreplaceable or hazardous materials.

Purpose of the Study:

  • Quantify heat generation from 785-nm NIR laser illumination on various colors.
  • Assess the thermal hazards associated with Raman analysis.
  • Develop safety guidelines for analyzing diverse sample types.

Main Methods:

  • Illuminated an extensive color array with a 785-nm NIR laser to quantify heat.
  • Used thermography to predict sample thermal response.

  • Conducted experimental analyses on flammable solvents, propellants, and explosives.

    • Main Results:

    • Darker colors absorbed more laser energy, leading to higher temperatures.
    • Visible color is not a perfect predictor of 785-nm absorption.
    • Thermal response varied significantly across different material types, including explosives and solvents.

    Conclusions:

    • Raman spectroscopy's 'nondestructive' nature is not absolute; laser-induced heating poses a risk.
    • Thermography offers a useful, albeit imperfect, method for predicting thermal responses.
    • Safety guidelines are crucial for mitigating risks during Raman analysis of sensitive materials.
