REFLEXⅢ基质辅助激光解析电离时间飞行(MALDI-TOF)质谱仪的特点及应用

The Characteristics and Applications of REFELEX I MALDI-TOF

REFLEAⅢ基质辅助激光解析电离时间飞行(MALDI-TOF)质谱仪(图1)是布鲁克公司推出的世界上最灵敏的MALDI-TOF质谱仪。该仪器配有自动制样机,无网离子的延迟引出技术,无网双聚焦反射器,除可测各种分子的分子量外,还可通过源后分解谱(Post Source decomposition,PSD)得到结构信息,是当前研究蛋白质组必不可少的质谱仪。本文对该仪器的主要优点,结构特点,仪器主要配置及应用等作了简要介绍。

REFELEX Ⅲ MALDI-TOF is the most sensitive MALDI-TOF mass spectrometer (MS) in the world . With our patented gridless pulse ion extraction (PIE), and gridless double focusing reflec-tron design, it can measure molecular weight of a molecule with high precision and give structural information with post source decomposition (PSD) analysis. It is an ideal MS instrument for researchers especially those who are working on the proteome project. In this article , we will decribe some of the characteristics of the intrument , its basic design and some applications.
