New technologies from recent acquisitions enable Bruker to offer additional, complementary high-performance analytical solutions and new compact, easy-to-use and affordable turn-key systems. With today's product introductions Bruker addresses an expanding array of life science, pharma-biotech, clinical research, food, petro-chem, environmental, homeland security, materials and nanoscience, as well as academic research and educational markets. The new Bruker products and solutions launched at Pittcon 2011 include: Mass Spectrometry and Separations: maXis 4G(TM): the breakthrough maXis 4G(TM) UHR-QTOF once again redefines high performance mass spectrometry by offering Full Sensitivity Resolution (FSR) of greater than 60,000 and mass accuracy better than 600 ppb. Other high-end QTOF systems may nominally reach 40,000 resolution, but only at the expense of a dramatic sensitivity loss by large factors due to special resolution-enhancing, but sensitivity degrading techniques like ion beam slicing, W-mode, etc. The maXis 4G is very unique and maintains its maximum sensitivity even at full mass resolution, and even while acquiring at up to 30 Hz speed during UHPLC separations. This completely unique highest performance envelope permits truly simultaneous discovery, identification and quantitation of low-level compounds or metabolites in a single maXis 4G LC-MS/MS run.

用的是安捷伦的ADC,成本马上超过FT了。
这个是Maxis4G的Ultramarker:

谢谢分享。

我算了算,我们现在的水平大概在4万左右——80cm上有1万4~1万6,在2米上我们应该可以做到4万。如果采用一些MALDITOF的技术,增加高压,我们也应给能做到5万吧,不过估计很多成本就会上升。

做事情还是要将就得失。如果做5万的LCTOF,先进性上赢不了bruker,国内无聊的人会说闲话;实用性上其实5万的没什么用,客户不多,也回不了本。

质谱超过200万实际意义不大。

如果是500万RMB一台的话,我都能做个FTMS了
