Method and apparatus for detecing materials in a liquid

摘要: A liquid carrier, such as water, containing trace amounts of material to be detected, organic materials, is passed through a first membrane separator for separating the carrier from detected. The detected passes and vapor into permanent gas atmosphere on downstream side thereof. vaporized separated gaseous by second analyzed, mass spectrometer, detection. system useful detection liquids including mineral oil prospecting in bodies water streams, rivers, lakes oceans their tributaries waterheads tracking fish vessels water.
