WHAT IS UV-c LIGHT?
UV-C is a type of ultraviolet light that has wavelengths between 200 – 280 nanometers (nm). Light within those wavelengths can be used for disinfection.
UV-C LIGHT DISINFECT?
UV light with wavelengths between 100nm and 280nm has the ability to inactivate microorganisms. The light is absorbed by the DNA and RNA of microorganisms, which causes the DNA and/or RNA structure to form new bonds between adjacent nucleotides. This results in the dimerization of adjacent molecules (particularly thymine). This occurrence in the DNA and RNA of viruses and bacteria makes it impossible for the microorganisms to replicate and infect.
WHAT IS UVGI?
UVGI (Ultraviolet Germicidal Irradiation) is a disinfection method that uses UV-C short-wavelength ultraviolet light to kill and inactivate microorganisms, such as germs, viruses and bacteria by destroying nucleic acids and disrupting their DNA. The optimal germicidal wavelength is 254 nm.
The application of UVGI to disinfection has been an accepted practice since the mid-20th century. This method has been employed to disinfect air, water and surfaces.
