Bruker Daltonics Launches APOLLO™ II Dual Source for Apex®-Qe FTMS

Bruker Daltonics has announced the APOLLO™ II Dual Source for its apex^® line of hybrid Q-q-FTMS mass spectrometers at Pittcon 2006. 

The design of the APOLLO II Dual Source is based on a wide aperture two-stage ion funnel with simultaneous integration of a MALDI and an ESI source.

This design makes switching between ESI and MALDI instantaneous and trivial, while providing sensitivity for both modes of FTMS operation.

With the introduction of the APOLLO II Dual Source, Bruker Daltonics has now combined the high sensitivity performance of the ion funnel with the versatility and convenience of a dual ESI and MALDI source.

Under ESI operation, the source provides all the sensitivity improvements of the previously launched APOLLO II ESI source, specifically attomole levels of detection for on-column loading.

This also translates into an overall increase in the speed of analysis as the FTMS analyzer can be filled quickly with the high flux source.

For MALDI, the APOLLO II Dual Source supports the industry standard MTP format with options of 96 and 384 spot targets, including the AnchorChip™ family of targets.

The sensitivity performance of the MALDI source (attomole level sample loading) is facilitated by efficient ion cooling, which has the additional benefit of enabling the use of a wider variety of matrices that can be tailored to specific applications.

"It's going to have tremendous applications in improving mass accuracy and aiding proteomics research, especially in shotgun proteomics," said Dr. Jon Amster, Professor of Chemistry at the University of Georgia.

Bruker Daltonics will exhibit at booth #3155 at Pittcon 2006.
