Real-time gas-chromatography mass-spectrometry trace vapor detection

摘要: A gas flow distribution system accumulates a sample from bearing carrier in micro-accumulator, delivers it using to chromatography column, and supplies the column facilitate separation of into components transport mass spectrometer for trace vapor detection analysis or testing real time. The is made inert configured have low dead volume improved performance accuracy detection. External valves are employed easy management balance minimize operation time continuous accumulation, delivery, sample. delivery an electrically heated cold trap as micro-accumulator can be performed extremely fast. By further combining accumulation phase phase, achieved. Because step delivering quickly, resume quickly nearly efficiency.
