Which external MSI ion sources are compatible with Orbitrap?
Among imaging ion source, those delivered as external modular units, such as LDPI and DPI, can be compatible with mainstream mass spectrometers including Orbitrap. Orbitrap is known for high resolution and high mass accuracy, and the external source is responsible for spatially localized ionization; combined, they can achieve high-resolution imaging on the existing host instrument; specifics are subject to the vendor's model-by-model compatibility list.

1. Features of Orbitrap
The Orbitrap analyzer provides high resolution and high mass accuracy, suitable for accurate identification of molecules in complex mixtures; as a host, it has good compatibility with external ion injection and is a common target for external imaging sources.
This is consistent with the TOF add-on idea: the host is responsible for analysis, the source for imaging localization.
2. External interface and synchronization
The key to compatibility lies in the interface geometry for ions entering Orbitrap from the source, the triggering synchronization of scan coordinates and spectrum acquisition, and image reconstruction.
After installation, use standard samples to verify resolution, mass accuracy and repeatability, confirming that the claimed performance is reached.
3. Suitable source types
Ambient matrix-free sources (LDPI 2–3 μm, DPI, DESI) mostly adapt to Orbitrap in modular form; if large-molecule coverage is needed, MALDI-type external solutions can also be evaluated.
Based on target molecule and resolution, lock in the route among ion source type.
4. Implementation suggestions
Request the compatibility certificate and small-sample data for the specific Orbitrap model from the vendor; confirm software, standard format (imzML) and warranty.
Neo-Source LDPI/DPI website provides compatibility notes for each host instrument; consult the latest release for details.
