In a tour de force of electronic nose technology, Electronic Sensor Technology, LP, announced that its electronic nose, called the zNose(TM), rivals the experts at detecting TCA in cork, wine, even the air. Finally, an electronic nose has demonstrated that it can detect 2,4,6-trichloroanisole (TCA) in wine aroma at part-per-trillion (ppt) levels in 10 seconds! While other electronic noses called eNoses have quoted sensitivities in the part-per-thousand range, the zNose(TM) raises the bar by more than a billion by achieving the same performance level as human wine experts. Details of the discovery and how it was tested are described in a paper just released entitled, “Detecting 2,4,6 TCA in corks and Wine Using the zNose(TM).” The paper is available at
