三种受阻胺氮氧自由基光稳定剂的电喷雾电离质谱

ESI-MS of Three Hindered Amine Free Radical Stabilizers

本文采用电喷雾电离质谱 ( ESI-MS)技术测试了三种受阻胺氮氧自由基光稳定剂 ,用 ESI-MS不仅得到了明显的准分子离子峰 ,而且通过其二级电离获得了更多的碎片信息 。

This article briefly described the characteristic mass spectra and structures of three hindered amine free radical stabilizeres. ESI-MS technology is applied on three hindered amine free radical stabilizers. With ESI-MS, not only the quasi-molecular ion peak, but much more fragment information by the further ionization is aquired. So it provides reliable structure information for the samples.
