MS/MS Option Time-of-Flight SIMS
Product Overview
The Parallel Imaging MS/MS Option enhances TOF-SIMS instruments by enabling simultaneous acquisition of MS¹ and MS² data. This capability allows for high-speed, high-sensitivity tandem mass spectrometry of the outermost surface of materials, facilitating detailed molecular structure analysis and imaging. By integrating a tandem mass spectrometer (MS²) with a conventional TOF-SIMS analyzer (MS¹), users can obtain comprehensive chemical information from the same measurement field.
Key Features
- Simultaneous MS¹ and MS² Acquisition: Enables parallel collection of TOF-SIMS and tandem MS data from the same analytical region, ensuring perfect spatial alignment between MS¹ and MS² images.
- Precursor Ion Selection: Utilizes a precursor selector to extract specified secondary ions, allowing for targeted analysis of molecular structures.
- Simplified Spectral Interpretation: MS² spectra provide simpler patterns compared to complex MS¹ spectra, facilitating easier identification of molecular structures such as terminal groups, linear chains, or double bonds.
- High Spatial Resolution: Achieves high-resolution imaging, enabling detailed visualization of molecular distributions on the sample surface.
- Enhanced Sensitivity: Provides high-sensitivity detection of surface molecules, making it suitable for analyzing trace components and contaminants.
