FOR IMMEDIATE RELEASE
Incorporating a New Spiral TOF Ion Optic System Capable of High Resolution Mass Analysis over a Wide Molecular Weight Range
JEOL Ltd. (Gon’emon Kurihara, President) announced a new spiral MALDI-TOF mass spectrometer, JMS-S3000, to be distributed in May 2010.
The JMS-S3000 is a MALDI-TOF MS incorporating JEOL’s original spiral TOF ion optic system. Featuring unprecedented levels of mass resolution and sensitivity, the system has been acknowledged for its distinctive capabilities in many scientific studies.
The JMS-S3000 is a leading analytical tool, suitable for changing research needs in areas of synthetic polymers, material science, and biological polymers.
[ Features ]
- High mass resolution and sensitivity over a wide mass range
Since many of synthetic polymers have varied molecular weight distributions, analysis of such samples requires high mass resolution and sensitivity in a wide molecular weight range. The JMS-S3000, incorporating JEOL’s unique Spiral TOF ion optic system, is superior to others in these areas.
- Optional linear TOF
This is effective for measurement of high molecular weight ions and analysis of samples subject to self-fragmentation.
- Optional TOF/TOF
This configuration enables MS/MS analysis by high energy collision-induced dissociation. The system, featuring a high precursor ion selection capability, allows the operator to select and monitor only monoisotopic ions in product ion spectral data. It is especially effective for analysis of complex product ion spectra.
