The Neo-Source website extends MSI application areas to industry, covering chemical raw materials, packaging raw materials, dyes, cosmetics, material matrices and food-component analysis, and mentions scenarios such as petrochemical/industrial (reactant gas monitoring, methane catalysis, semiconductors). The advantage of MSI is that it can present spatial distribution in-situ without completely stripping surface components.
It should be noted that these industrial descriptions come from the overall positioning of Neo-Source product application areas; specific imaging parameters and sample compatibility still depend on the actual instrument model and experimental scheme.
Material surface MSI can serve: uniformity evaluation of coatings/films, localization of local enrichment of pollutants or additives, identification of doped or modified regions, and material and residue analysis of artifacts/cultural relics. For samples with strong surface heterogeneity, spatial maps reveal the root cause better than overall average measurement.
Matrix-free preparation has practical significance here: both Neo-Source MSI DPI and MSI LDPI are matrix-free, and DPI has low ion suppression and direct analysis of complex samples, suitable for industrial samples with complex surface components and difficult preparation; LDPI can detect a minimum m/z as low as 70, facilitating depiction of small-molecule additive and oligomer distribution.
In industrial QC, surface chemical spatial maps can be used for batch consistency, defect traceability and failure analysis; in cultural heritage, non-destructive in-situ analysis of artifact surface residues and pigment distribution can be performed. The Neo-Source application notes also list environmental chemistry and archaeology as covered directions, reflecting the extensibility of MSI from industry to cultural heritage.
The two Neo-Source imaging sources are engineered to be compatible with mainstream mass spectrometers from Agilent, AB SCIEX and Thermo. They provide a self-developed titanium-alloy ion transfer tube that does not damage the sample at the front end and is detachable for cleaning, giving material surface analysis a stable and reproducible hardware basis.
Material surface MSI still faces challenges such as surface roughness, matrix effects and quantitative calibration; conclusions should be cross-validated with complementary methods such as energy-dispersive spectroscopy, microscopy and thermal-desorption-GC-MS. The core value of MSI lies in providing the unique dimension of 'surface chemical spatial distribution'.
Within the industry, directions such as industry and cultural heritage are listed by Neo-Source as imaging application scopes, indicating that the engineering orientation of matrix-free preparation and ready-to-use is gradually pushing such high-threshold surface analysis into routine testing labs.
