Comprehensive Fractionation of Herbal Medicine Components by PDA-ELSD triggered Preparative LC

User Benefits

- Comprehensive fractionation can be performed without missing non-UV absorbing compounds. - Graphical user interface provides easy and labor-saving operation for fractionation settings. - Smooth transfer from preliminary analytical LC to preparative purification LC is possible because the both LC analyses can be controlled by the same software.

Introduction

A preparative LC is widely known as a means of purifying target compounds from mixtures. An ultraviolet (UV) detector or a photodiode array detector (PDA) is commonly used in ordinary preparative LC. A preparative purification of all compounds without any omission is not possible because these detectors cannot detect non-UV absorbing compounds. This article introduces a comprehensive fractionation for both UV absorbing and non-UV absorbing compounds using a newly designed PDA-ELSD triggered preparative LC that equips an evaporative light scattering detector (ELSD) in addition to the PDA.
