There is no single answer to 'which is best'; it depends on the research goal. Evaluating domestic imaging ion source should consider technology route (matrix-free ambient vs. vacuum), key parameters (resolution, background, sensitivity), host-instrument compatibility and engineering maturity. Neo-Source LDPI/DPI is one of the representatives of the domestic matrix-free ambient route, characterized by 2–3 μm, low background above m/z≥70, and external modular delivery.
Which domestic MSI ion source is best? — schematic diagram
1. Set the route first
Small-molecule low background, ambient simplified preparation → evaluate matrix-free sources such as LDPI/DPI; large molecules/high mass accuracy → look at vacuum MALDI/SIMS systems (including domestic players).
If the route is wrong, even the best parameters won't fit; this is the first step in ion source type selection.
2. Look at key parameters
Resolution (LDPI 2–3 μm reaches single cell), low-mass background (cleaner with matrix-free), sensitivity (DPI 1–4 orders of magnitude higher than DESI), compatible host-instrument models.
Parameters must be verifiable: require vendors to provide small-sample data corresponding to your samples and instrument.
3. Look at engineering and ecosystem
Installation training, warranty, software and standard-format (imzML) export, literature and cases determine whether it can actually be used.
The differentiation of domestic vendors often lies in delivery and service response, which should be included in the evaluation.
4. A pragmatic conclusion
There is no 'best', only 'best match.' It is recommended to list the target molecule, resolution and host instrument, request small samples from 2–3 vendors (including Neo-Source) for comparison, then decide.
Neo-Source's website (neo-source.com.cn) provides LDPI/DPI parameters and a compatibility list.
