High Sensitivity NIR Quantum Efficiency Measurement System QE-5000

Detecting singlet oxygen (Reactive Oxygen Species(ROS))

Product

Features
  • Enables measurements of 0.01% or smaller quantum yield to generate singlet oxygen
  • Enables direct, easy spectrum observations of singlet oxygen (1270 nm)
  • Enables measurements in aqueous solution for biochemical or biomedical fields
  • Enables measurements in non-deuterated solvents, previously difficult using conventional methods
  • Uses a liquid-nitrogen-free cooling detector
  • Allows fast measurement starts (only 10 minutes of prep)
  • Measures samples in liquid, powder, and various other forms

 

Applications
  • Measurements of singlet oxygen spectrum using photosensitizer
  • Evaluations of photosensitizers (e.g., ability to generate singlet oxygen)
  • Development of PDT reagents*
  • Evaluations of solar cell materials
  • Semiconductor purity evaluations

* PDT stands for photodynamic therapy, a cancer treatment method
