Abstract

Liquid Chromatography (LC) is an important method of physical separation of compounds in liquids. The fields of application are wide-ranging such as food, drug and environmental analysis, process monitoring in chemical industry and bioreactors [1-3]. Therefore, LC detectors require a broad range of compounds that can be detected when eluting from the LC column. Common universal detectors use different detection principles and therefore, different characteristics of the compounds, and can be categorized in light based detectors (fluorescence, absorption, refraction and scattering) and resistive detectors [4]. However, the sample preparation process for some of these detectors is time consuming and elaborate to make the compounds detectable, e.g. by optical detectors [5]. Other detectors such as mass spectrometers imply high instrumental effort with high purchasing and operating costs. Nevertheless, mass spectrometry adds a second dimension of separation for better compound identification [4]. These examples show that universal and inexpensive detectors without elaborate sample preparation would ease LC.
