Bruker Daltonics Introduces Novel LC/GC Time-of-Flight Mass Spectrometer micrOTOF™ II for LC/MS and GC/MS on One System : Bruker's next generation high-resolution API-TOF – now available for LC/MS and GC/MS on the same system – allows high-performance TOF analysis from polar to volatile analytes

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.
