BrukerDaltonics推出micrOTOFII新型LC／GCTOF質譜儀

Bruker Daltonics推出micrOTOF II ?新型LC/GC-TOF質譜儀，一套系統適用于LC/MS和GC/MS

2008年6月

丹佛，商業電訊，2008年6月2日，在ASMS 2008上，布魯克道爾頓宣布推出新版micrOTOF II ?API-TOF大氣壓下飛行時間質譜儀，同時，有一個新的可選項GC-APCI接口，用于使用單個平臺做GC-MS和LC-MS，具有前所未有的分析靈活性。

布魯克道爾頓提高了其著名的高分辨API-TOF系統——micrOTOF?的性能，并更進一步地提高分辨率至16,500，質量準確度至1～2 ppm。更高的精確質量加上SmartFormula?智能化學式計算軟件，使micrOTOF II 成為該系列中最出眾的儀器，用戶可高度確信地進行化學式測定和鑒定，甚至在復雜的混合物中。

增加的分析靈活性：micrOTOF II 現在可使用新型GC-APCI接口，可在同一臺儀器上做GC/TOF-MS。這種成本效益的組合，使用戶不必再專門買一臺GC/TOF，只需幾分鐘，無需工具，就可切換LC和GC方式，在一個平臺上實現出色的質量準確度和分辨率。micrOTOF II是第一臺通用的、用于GC和LC分析的臺式精確質量測定工具。

典型的GC/TOF-MS應用包括：多目標物篩選，在GC色譜和代謝組學研究中鑒定未知峰。micrOTOF II高達20 Hz 譜圖到磁盤的采集速率，可對GC產生的尖峰達到瞬時清晰度。所有著名的已用在LC/TOF-MS中的Bruker軟件工具，比如智能化學式計算Smartformula?，或用于目標物篩選TargetAnalysis?，均可立即應用于GC/TOF分析。

GC-APCI源能被進一步地升級為激光源APLI（大氣壓下激光電離），這是一項用于特殊應用的新型離子化技術，比如用于食品和水中的PAH的超痕量檢測。在此類應用中，APLI技術可大幅提高靈敏度和專一性。

關于新型GC-APCI接口的演講，將在周二的Bruker Workshop給出。

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.
