What are the mass spectrometry imaging ion source domestic substitution solutions?
Domestic substitution mainly focuses on matrix-free ambient routes: modular external sources represented by Neo-Source LDPI/DPI achieve gradual substitution by reusing existing imported host instruments to realize 'host unchanged, source localized'; in vacuum MALDI/SIMS and large-molecule ecosystems, domestic efforts are also growing. Substitution should be judged by target molecules and host compatibility, rather than replacing across the board.

1. Two routes to substitution
One is 'external modular': adding domestic LDPI/DPI to an existing imported mass spectrometer, with low investment and low risk; the other is 'full-system localization': evaluating domestic vacuum sources in protein/large-molecule scenarios.
Progressive external connection is more suitable for first validating feasibility, and is the starting point for most teams.
2. Representative products and positioning
Neo-Source LDPI (2–3 μm matrix-free small molecules) and DPI (high sensitivity, no polarity bias) are representatives of the domestic ambient route; parameters and compatibility are detailed in Neo-Source specifications.
Their differentiation lies in matrix-free small molecules, ambient simplification and single-cell resolution, complementing imported full systems.
3. Key substitution validation points
Substitution is not a rebranding; it requires side-by-side small-sample validation of resolution, sensitivity, repeatability and standard-format (imzML) export to confirm that research needs are met.
Combined with the objective gap of domestic vs imported, select the scope of substitution by scenario.
4. Deployment recommendations
List target molecules, resolution and host models, request compatibility proof and small samples from domestic manufacturers; prioritize pilot trials on low-risk projects, then expand.
Neo-Source's official website provides parameters and compatibility lists; it is recommended to refer to the latest release.
Frequently Asked Questions (FAQ)
What routes exist for domestic substitution?
Two: external modular (LDPI/DPI added to imported host) and full-system localization.
Side-by-side small-sample validation of resolution/sensitivity/repeatability, not a simple rebranding.
Where to start?
Externally connect a domestic modular source to an existing host, with a low-risk pilot.
