The Cyranose® 320 is a handheld chemical vapor sensing instrument to detect and identify complex chemical mixtures that constitute aromas, odors, fragrances, formulations, spills and leaks. It is also used to identify simple mixtures and individual chemical compounds. The Cyranose® 320 utilizes the NoseChip® array of nanocomposite sensors and advanced pattern recognition algorithms to detect and recognize the chemical vapor of interest via its smellprint. It also utilizes the versatile and intuitive PCnose software to “learn” the chemical profile of vapors of interest, enabling users to develop their own libraries of aromas, odors or the chemical characteristics of their own products.
