There is also a new technology soon to be on the market called Predictive Containment which uses sensors and artificial intelligence (machine learning) to monitor a fume hood’s containment in real time. These “smart” hoods will be able to monitor the hood’s containment continuously.

Another real-time way to test containment is to monitor the air quality just outside the fume hood. This concept acknowledges that the fume hood will likely have some loss of containment. When loss of containment occurs, this air monitoring system will detect fugitive chemicals and increase the number of ACH to dilute these contaminants to a safe level.

Lastly, it should be noted, that because SF6 has been identified as harmful to the atmosphere (greenhouse gas), there is a movement underway to change the tests that use SF6. The most talked about option is to change from SF6 gas to isopropyl alcohol (IPA).

The next few years will likely bring much change to the world of fume hood testing, including a more global requirement to perform regular testing, for now, any testing is better than no testing.
