Claim:
1. A system for analyzing gaseous samples, the system comprising: a sensing tape having a first side and a second side, said first side being a front side and said second side being a reverse side, said first side being exposed to a first stream of a first gaseous sample and said second side being exposed to a second stream of a second gaseous sample; a first sensing assembly for sensing a concentration of a first substance from said first stream from said first side of said sensing tape, said first sensing assembly including a first sensor; a second sensing assembly for sensing a concentration of a second substance from said second stream from said second side of said sensing tape, said second sensing assembly including a second sensor; wherein said sensing tape is mounted on at least one reel, a rotation of said at least one reel causing a first side of said sensing tape to move adjacently past said first sensor and causing said second side of said sensing tape to move adjacently past said second sensor; when said first side of said sensing tape is moved past said first sensor, said first sensor senses a quality of said first side after said first side has been exposed to said first stream; when said second side of said sensing tape is moved past said second sensor, said second sensor senses a quality of said second side after said second side has been exposed to said second stream.
