A reproducible bio-decontamination process requires reliable means of controlling and monitoring the environment. While knowing the operating principle and specifications of your measurement instrument is important, understanding the different measurement parameters and their dependencies is equally important.
 
In this webinar, we discuss the methods for calculating different humidity and vaporized hydrogen peroxide variables, such as: relative saturation, parts per million, and mixture dew point temperature. A better understanding of these variables can help you to take this knowledge into practice, such as calculating VH2O2 concentrations in different types of bio-decontamination processes.
 
Webinar attendees will receive a downloadable Excel calculator tool for vH2O2 variables.
 
Outline:
• The theory behind vaporized hydrogen peroxide measurement
• Overview of common calculation formulas
• Practical calculation examples for different VH2O2 bio-decontamination methods:
  • Open circulation
  • Closed circulation
  • Free evaporation
