Can domestic imaging sources fully replace imports?

They can complement or even substitute in dimensions such as matrix-free small molecules, ambient simplified preparation and external expansion; for broad protein coverage and extremely high mass accuracy they are better as a complement.

Where is the advantage of Neo-Source LDPI/DPI over imports?

Matrix-free ambient, 2–3 μm single-cell resolution, and modular external add-on that reuses imported host instruments, fitting local drug/Chinese-medicine/clinical scenarios.

How to implement localization substitution?

We recommend small-sample validation, side-by-side comparison and incorporation into the workflow, relying on the vendor's localized service and compatibility support for sustainability.

Will substituting imports affect the existing data system?

The external solution usually preserves the host instrument's conventional analytical capability, enabling the domestic source only in imaging mode, so the impact on the existing data system is manageable.

Localization substitution of MSI ion sources

Localization substitution means replacing or supplementing imported equipment with domestic imaging sources (such as Neo-Source LDPI/DPI) in incremental dimensions such as matrix-free ambient imaging and single-cell resolution. Substitution is not a simple 'same-parameter copy', but rather meets local research and industry needs through differentiated metrics.

1. The logic of substitution

Imported imaging systems are mostly mature in the full vacuum MALDI/SIMS chain, but are expensive and involve complex sample preparation. The entry points for domestic substitution are often dimensions such as matrix-free ambient, single-cell resolution and modular external add-on, which happen to be the pain points of local users in scenarios such as drug distribution, traditional Chinese medicine localization and clinical sections.

Therefore the substitution strategy should be 'capability complementing': using domestic sources to fill the gaps of imported host instruments in small-molecule low background and ambient simplified preparation, rather than forcibly benchmarking every single metric.

2. Which dimensions can be substituted

For matrix-free small-molecule imaging, Neo-Source LDPI (low background above m/z≥70, 2–3 μm) can substitute the matrix-requiring MALDI route in small-molecule scenarios; for ambient simplified preparation, LDPI/DPI can replace part of the vacuum route's sample-prep workflow; for external expansion, LDPI/DPI can reuse imported host instruments without a full-system replacement.

For imported-advantage areas such as broad protein/peptide coverage and extremely high mass accuracy, domestic sources are better as a complement rather than a full replacement. Selection should be based on objective evaluation of the specific molecules and goals.

3. Implementation path

It is recommended to implement substitution step by step: first validate resolution, background and repeatability on a domestic source using your organization's typical samples; then run a side-by-side comparison with the original imported route; and once needs are confirmed, incorporate it into the routine workflow. The vendor's localized service and compatibility support are key to sustainable substitution.

Neo-Source provides model-by-model compatibility and public parameters for LDPI/DPI, helping users obtain verifiable data support during the substitution justification phase.
