What is SIMS High-Resolution Imaging?
SIMS High-Resolution Imaging is a surface-sensitive mass spectrometry technique that provides chemical imaging at nanometer-scale resolution. A focused ion beam induces the emission of secondary ions from the sample surface, which are analyzed to generate highly detailed 2D or 3D maps of elemental, isotopic, and molecular distributions. Its unparalleled spatial resolution and surface specificity make it ideal for studying interfaces, thin films, and surface heterogeneity. This technique delivers rich chemical information with exceptional precision, enabling insights that are difficult to achieve with other imaging modalities.

FAQs
What types of samples are suitable for SIMS High-Resolution Imaging?
SIMS is best suited for solid samples, including biological tissues, cells, polymers, thin films, coatings, semiconductors, and other inorganic or hybrid materials. Samples must be compatible with high-vacuum conditions and have a relatively flat, clean surface to ensure optimal data quality.
What spatial resolution can SIMS High-Resolution Imaging achieve?
Depending on the instrument configuration and sample type, SIMS can achieve spatial resolutions down to the nanometer scale. This makes it one of the highest-resolution mass spectrometry imaging techniques available for surface chemical analysis.
What types of molecules or elements can be detected by SIMS?
SIMS is highly versatile and can detect elemental ions, isotopes, and low-mass molecular fragments. It is particularly powerful for elemental and isotopic mapping, while larger intact biomolecules may fragment during ionization.
What sample preparation is required for SIMS analysis?
Samples should be clean, dry, and securely mounted on a conductive substrate. Biological samples often require cryo-sectioning or freeze-drying to preserve spatial integrity and vacuum compatibility. Please contact us before starting the project, we will provide detailed instructions on sample preparation.
What is the typical turnaround time for SIMS High-Resolution Imaging, and can I discuss my experimental design?
Our standard turnaround time is 4–6 weeks from sample receipt to delivery of processed results. We also support remote, real-time consultations to discuss your experimental design, sample preparation, and project requirements, ensuring your workflow is tailored to your research needs.

Sample Preparation Guidelines
SIMS analysis takes place in an Ultra-High Vacuum (UHV). Samples must be perfectly dry, flat, and vacuum-compatible.
| Parameter | Requirement | Technical Reason |
|---|---|---|
| Surface Topography | Ultra-Flat / Polished | Rough surfaces deflect the primary ion beam, causing shadowing and signal distortion. Samples should be polished to a mirror finish if possible. |
| Vacuum Compatibility | Zero Outgassing | Samples must be fully dry. No wet tissues, volatile solvents, or porous materials that outgas (which ruins the high vacuum). |
| Conductivity | Conductive Surface | Insulating samples (e.g., glass, biological tissue) will accumulate charge. We may apply a thin Gold or Carbon coating to ensure stability. |
| Fixation (Bio) | High-Pressure Freezing / Freeze-Fracture | Chemical fixatives can redistribute ions. Cryo-fixation is preferred for accurate electrolyte mapping. |
| Size Constraints | Small (<10 mm diameter) | SIMS sample holders are typically very restricted in size compared to MALDI or SEM. |
Before starting sample preparation, please consult with our team to discuss your sample type and experimental goals, ensuring optimal preparation and smooth workflow.
