BrukerDaltonics推出micrOTOFII新型LC／GCTOF质谱仪

Bruker Daltonics推出micrOTOF II ™新型LC/GC-TOF质谱仪，一套系统适用于LC/MS和GC/MS

2008年6月

丹佛，商业电讯，2008年6月2日，在ASMS 2008上，布鲁克道尔顿宣布推出新版micrOTOF II ™API-TOF大气压下飞行时间质谱仪，同时，有一个新的可选项GC-APCI接口，用于使用单个平台做GC-MS和LC-MS，具有前所未有的分析灵活性。

布鲁克道尔顿提高了其著名的高分辨API-TOF系统——micrOTOF™的性能，并更进一步地提高分辨率至16,500，质量准确度至1～2 ppm。更高的精确质量加上SmartFormula™智能化学式计算软件，使micrOTOF II 成为该系列中最出众的仪器，用户可高度确信地进行化学式测定和鉴定，甚至在复杂的混合物中。

增加的分析灵活性：micrOTOF II 现在可使用新型GC-APCI接口，可在同一台仪器上做GC/TOF-MS。这种成本效益的组合，使用户不必再专门买一台GC/TOF，只需几分钟，无需工具，就可切换LC和GC方式，在一个平台上实现出色的质量准确度和分辨率。micrOTOF II是第一台通用的、用于GC和LC分析的台式精确质量测定工具。

典型的GC/TOF-MS应用包括：多目标物筛选，在GC色谱和代谢组学研究中鉴定未知峰。micrOTOF II高达20 Hz 谱图到磁盘的采集速率，可对GC产生的尖峰达到瞬时清晰度。所有著名的已用在LC/TOF-MS中的Bruker软件工具，比如智能化学式计算Smartformula™，或用于目标物筛选TargetAnalysis™，均可立即应用于GC/TOF分析。

GC-APCI源能被进一步地升级为激光源APLI（大气压下激光电离），这是一项用于特殊应用的新型离子化技术，比如用于食品和水中的PAH的超痕量检测。在此类应用中，APLI技术可大幅提高灵敏度和专一性。

关于新型GC-APCI接口的演讲，将在周二的Bruker Workshop给出。

Bruker Daltonics Introduces Novel LC/GC Time-of-Flight Mass Spectrometer micrOTOF™ II for LC/MS and GC/MS on One System
. June 2008
 

DENVER--(BUSINESS WIRE)--June 2, 2008--At ASMS 2008, Bruker Daltonics today announced the new further enhanced micrOTOF II API-TOF mass spectrometer, as well as a novel, optional GC-APCI Interface for a single high-performance platform for LC/MS and GC/MS with unprecedented analyte flexibility.

Bruker Daltonics has enhanced its well-known high-resolution API-TOF system, the micrOTOF™, even further improving its resolution to greater than 16,500 and its mass accuracy to 1-2 ppm. Even better mass accuracy plus SmartFormula™ makes the micrOTOF II an outstanding instrument in its class, providing the user with high confidence in formula determination and identification, even in complex mixtures.

For additional analytical flexibility, the micrOTOF II now can be equipped with a new GC-APCI (atmospheric pressure chemical ionization) interface which allows GC/TOF-MS analysis on the same instrument. This cost-effective combination obviates the need for a dedicated GC/TOF, offering instead outstanding mass accuracy and resolution on a single platform with simple interchange between LC and GC operation in a few minutes without tools. The micrOTOF II the first universal bench-top accurate mass tool for GC and LC chemical analysis.

Typical applications for GC/TOF-MS include multiple target screening, identification of unknown peaks in the GC chromatogram and metabolomics studies. The high acquisition speed of 20 Hz spectra-to-disk of the micrOTOF II allows temporal resolution of the sharp peaks which are generated by a GC. All renowned Bruker software tools to deliver real answers from LC/TOF-MS data, such as Smartformula™ for molecular sum formula generation, or TargetAnalysis™ for screening can be immediately applied to GC/TOF analysis.

The GC-APCI source can be further upgraded with a laser to APLI (atmospheric pressure laser ionization) which is an exciting new ionization technique for specific applications such as ultra-trace determination of PAH in food and water. The APLI technique delivers dramatic improvements in sensitivity and selectivity for these applications.

A presentation on the new GC-APCI Interface will be given in the Bruker Workshop on Tuesday, June 3rd from 12-1 pm in Room 406 of the Colorado Convention Center.

Additional information will be available at the Bruker Daltonics Exhibition Booth (#65) during the ASMS conference and at the Bruker Daltonics Hospitality Suite from 7-11 pm on Monday June 2nd to Wednesday June 4th in the Windows room, Denver Sheraton.
