Confirmation of Synthesis of Organic EL Materials Using Direct Infusion Mass Spectrometry

User Benefits

- By injecting a sample using direct infusion into a single quadrupole mass spectrometer, confirmation of the synthesis of the main components can be simply achieved. - In-source CID enables simple estimation of chemical structure as well as confirmation of molecular weight.

Introduction

In chemical synthesis, confirmation of molecular weight by mass spectrometry is one of the common methods used for determining whether the synthesis was successful or not. When the composition of the analyte can be inferred in advance, such as for confirming synthesis, accurate mass measurement is not always necessary. In Application News No. 01-00266-EN, examples were introduced in which the synthesis of organic EL materials was confirmed and the molecular weight of the impurities contained was estimated using a high performance liquid chromatograph (HPLC) and a single quadrupole mass spectrometer. This Application News describes an example in which the molecular weight was confirmed by direct infusion and single quadrupole mass spectrometer in order to more easily confirm the synthesis of the main component.
