A leak detection apparatus includes an oxidation chamber, a chemical marker concentrator, a mass spectrometer (MS) ion trap and a scroll vacuum pump. Vapor samples carrying marker chemicals introduced into a tank, pipeline, or other containment are injected at sample injection point into an oxidation chamber. Oxygen from an oxygen source is fed into oxidation chamber to destroy or oxidize contaminates such as hydrocarbons in the vapor without destroying or oxidizing the chemical markers. Effluent from the oxidation chamber is passed to an elongate conduit with a metal foil or screen suspended within the conduit. The marker chemicals are attracted by a chemical coating on the foil/screen and released by heating the metal. The released marker chemicals are fed into a mass spec ion trap for leakage analysis and results."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and methods for monitoring leaks in underground storage tanks","description":"Leak detection system and method for monitoring leaks in underground and aboveground storage tanks, pipelines or other containments, including single, double or triple wall containments are provided.
