We have developed a combination of high-performance liquid chromatography (HPLC) and the chemical reaction interface mass spectrometry (CRIMS) method by using a Vestec Universal Interface (UI). This interface provides the extremely high degree of solvent removal that the CRIMS process requires. In doing so, we have produced an HPLC detector with the ability to carry out the element- and isotope-selective analyses with detection that is inherently: linear, structure-independent, sensitive, selective, comprehensive and flexible. The characteristics of the instrumentation and its performance are described.
我们通过使用Vestec通用接口（UI）开发了一种高效液相色谱（HPLC）与化学反应界面质谱（CRIMS）方法相结合的技术。该接口提供了CRIMS过程所需的极高程度的溶剂去除能力。通过这样做，我们制造出了一种HPLC检测器，它能够进行元素和同位素选择性分析，其检测具有固有的线性、与结构无关、灵敏、选择性强、全面且灵活的特点。文中描述了该仪器的特性及其性能。
