What makes the 3rd Generation ENose better than the First?
The 3rd Generation ENose is being made especially for use in the International Space Station. The 3rd Generation ENose is based on the 2nd Generation ENose. For the 2nd Generation ENose, we used the same basic sensor design as in the 1st, but we studied the polymers and how to make them, and have found ways to make them more sensitive than the ones used in the 1st Generation ENose. In the 2nd Generation, we detected chemical species at lower concentration than in the 1st Generation ENose. Also, in the 3rd Generation, we have added the ability to detect mercury and sulfur dioxide.
