Carbon Dioxide 4.5

High purity carbon dioxide is a key component in resonator gas mixtures, which are vital for gas lasers to be able to create light. Low levels of impurities ensure optimal performance of the laser.


High purity carbon dioxide is widely used in CO2 lasers as well as in laboratories.


  • Combined with nitrogen and helium to form a resonator gas mixture, which is essential for gas lasers to be able to create light. Low levels of impurities, particularly low levels of hydrocarbons and moisture, are vital for optimal laser performance and operation.
  • Various applications in laboratories.
