7 Airborne ROS

Inside High Voltage Controlled Pulse (HVCP) Chamber Short Lived ROS (few microseconds to seconds)

•OH

Hydroxyl Radicals

  • Highly Reactive
  • Leads to the formation of H2O2
  • Reactive with pollutants and starts decomposition by cracking
  • Destroys VOC by removing of a hydrogen (H) atom forming water (H2O) and alkyl Radical (R•)

₁O₂

Singlet Oxygen (Dioxidene)

  • Highly Reactive toward organic compounds
  • Participates in reaction to form H2O2
  • Paramagnetism
  • Attracts organic compounds that results in oxidation

O₂₋

Superoxide

  • Reactive oxygen ion - Anion
  • Free radical
  • HO2 hydroperoxyl
  • Paramagnetism
  • Attracts organic compounds that results in oxidation

O(3P)

Atomic Oxygen

  • Highly reactive and quickly bonds with molecules
  • Free Radical forms into O3

ONOO-

Peroxynitrite (Peroxonitrite)

  • Oxidant
  • Ion
  • Damages a wide array of molecules in cells. Including DNA & Proteins.

Exits HVCP Chamber Into Environment: Longer lived ROS (minutes to hours)

O₃

Ozone (Trioxygen)

  • Triatomic allotrope
  • Most powerful oxidant
  • Sanitizer
  • Decontamination
  • Destroys Mold, VOC, Etc.
  • Low levels are not powerful to be effective with ozone alone! We keep setpoints at 30ppb (parts per billion).
  • Half-life varies with atmospheric conditions such as temperature, humidity, and air movement.

H₂O₂

Hydrogen Peroxide - Gas Phased

  • Deodorize air
  • Oxidizer
  • Antiseptic
  • Sanitizer
  • Antimicrobial agent
  • Destroyed by light

Bonus: Created By Ozone And Hydrogen Peroxide

H₂O₃

Hydrogen Trioxide - Trioxidane

  • Active Antimicrobial formed through peroxone process with O3 and H2O2 mix
  • Approximately 12min half-life
