Electrospray ionization mass spectrometry (ESI‐MS) in conjunction with liquid chromatography (LC) can provide accurate quantitative data, but it is not well‐suited for the rapid screening (RS) of analytes incurred into complex matrices. This study was designed to determine the usefulness of ESI for rapid detection and quantitation of veterinary drugs from complex biological matrices under near real‐time conditions.

电喷雾电离快速筛选，无液相色谱柱：一种检测和定量动物组织和尿液中化学物质的灵敏方法。

电喷雾电离质谱（ESI-MS）结合液相色谱（LC）可以提供准确的定量数据，但不适用于快速筛查（RS）复杂基质中分析物的方法。本研究旨在确定ESI在近实时条件下对复杂生物基质中兽药的快速检测和定量分析的有用性。
