Title:
【発明の名称】ダイレクトフローインジェクション分析噴霧エレクトロスプレーとAPCI質量分析法
Document Type and Number:
Japanese Patent JP2002540385
Kind Code:
A
Abstract:
A method and apparatus for Flow Injection Analysis (FIA) into Atmospheric Pressure Ion sources (API) including Electrospray (ES) and Atmospheric Pressure Chemical Ionization (APCI) sources whereby the sampling and spray needles are one and the same. The sampling and spray needle configured with an autoinjector apparatus or used in manual injection is introduced directly into a mating ES or APCI probe configured in an API source. Such a sampling and spray needle eliminates the need for injector valves, transfer lines or additional fluid delivery systems in FIA into API sources interfaced to mass spectrometers or other chemical analyzers. The use of a sampling and spray needle configuration reduces component costs, liquid dead volume, sample dilution effects, and minimizes cross contamination effects, solvent consumption and waste while increasing sample throughput.
