Vigi e-nose Solutions Intelligent Odor Management Advanced autoGC platform delivering continuous ppb/ppt-level odor and VOCs speciation, enabling precise source identification and site-wide monitoring. Real-time odor mapping, threshold-based alerts and automated process control for reliable environmental supervision across industrial facilities. Ultra-Sensitive Odor Detection • Lower detection limits than human olfactory thresholds (e.g., H2S < 1 ppb) • Accurate quantification of odor intensity without prior training • True chemical speciation: sulfurs, mercaptans, VOCs, aldehydes, ketones, amines,...
