Does the novel fast-GC coupled with PTR-TOF-MS allow a significant advancement in detecting VOC emissions from plants?

isobaric isoprenoid compounds that cannot be identified by a direct PTR-TOF-MS the information provided by PTR-TOF-MS was investigated by using the BVOC emissions and monoterpenes. The performan...
