A notable feature of MSA is that the TOF section is polarized with a linear electric field that provides an enhanced mass resolution, a capability that is of importance at Mercury since a variety of species originating from the planet surface and exosphere is expected.
The strategy targets the two-ion-gun approach to maximize ionization with reduced damage, laser postionization to maximize ionization efficiency, and the implementation of an orbitrap device for ultrahigh mass resolution with tandem mass spectrometry capabilities.
The capability of high mass resolution, high mass accuracy, and on-tissue MS/MS provided evidence in the structural identification of pederin and pseudopederin in the tissue (Fig. 3).
Finnigan MAT in Germany introduced the Neptune MC-ICP-MS, a double focusing C-shape instrument with a large magnet providing 16% mass dispersion, movable collector array, and high resolution capability.
The miniature TOF MS was successfully developed with relative high mass resolution and wide ion kinetic energy distribution measurement capability which could be used to diagnose the cathodic vacuum arc discharge plasma.
This instrument is a modified version of the QSTAR XL (AB SCIEX, Framingham, MA) featuring a 20 kV DC C60 primary ion beam for SIMS, a translational sample stage that enables imaging experiments, tandem MS (MS/MS) capability via collision induced dissociation (CID), and high mass resolution (R > 10 000).
By applying nano-scaled materials to tunable platforms, scientists have greatly enhanced the capabilities of traditional MS-based techniques, by increasing mass resolution, mass range, mass intensities, to name a few.
Especially, a small extraction hole in the acceleration region was set for getting relative high mass resolution, an ion detector with a large rectangular effective area were designed for getting wide ion kinetic energy distribution measurement capability.
The mass resolution is measured with data.
The printer's image resolution capability is less than the given dpi numbers.
