Next Generation Sensors is a company developing a Handheld Molecular Contaminant Screener (HMCS) based on a portable mass spectrometer for early on-site detection of contaminants in the agri-food sector. The device offers application-specific capabilities to detect a contaminant of interest. HMCS can be used by food and feed companies, production factory workers, farmers, suppliers, and regulatory agencies at any point in the food supply chain.
