Analysis of Organic EL Materials and Impurities Using Single Quadrupole Mass Spectrometer

User Benefits

- The synthesis of organic EL materials can be easily confirmed using a single quadrupole mass spectrometer in the same space as an HPLC system. - Equipped standard with a heated DUIS^TM unit, the system can even ionize compounds with low polarity, such as polycyclic aromatics. - By combining a single quadrupole mass spectrometer with the HPLC unit, the system can be used to check for known impurities or easily predict the molecular weight of unknown impurities.

Introduction

Organic EL materials represent a family of mostly polycyclic aromatic light-emitting compounds used to make organic light- emitting diode displays and other products. Because high- quality organic EL materials are required for developing high performance displays, the concentration of impurities contained in the materials must be controlled and evaluated. This article describes an example of using a high performance liquid chromatograph and single quadrupole mass spectrometer to check the synthesis of organic EL materials and predict the molecular weights of impurities they contain.
