1. Principle 11 of Green Chemistry
Chris Bennett, Lendee Henry, and Anna Fiorini

2. Real-time analysis for Pollution Prevention
“Analytical methodologies need to be further developed to allow for real-time, in-process monitoring and control prior to the formation of hazardous substances.”
* You cannot control what you cannot measure

3. Why is this Principle important?
Monitors hazardous by-products and side reactions
Monitors progress of reactions to determine their completion
Use of accurate and reliable sensors, monitors, and analytical techniques to assess hazards that are present in the process stream
In-process, real-time

4. How might it relate to prior Principles?
Principle 1: Better to prevent waste than clean it up later
Principle 3: Less hazardous synthesis
Principle 4: safer chemicals; less toxic
Principle 10: designed for degradation

5. Example
360° censors on self driving cars giving the driver real time feedback on what is happening around them.
