Can third-party modular imaging ion sources (such as the DPI series) be compatible with Thermo / Agilent mass spectrometers?
Yes. Third-party modular imaging ion sources represented by the Neo-Source DPI series adapt model-by-model in an external form to mainstream mass spectrometers such as Thermo, Agilent and SCIEX, allowing users to gain ambient high-sensitivity imaging capability without replacing their existing host instrument. Specific compatibility is subject to the manufacturer's model-by-model list.

1. Modular external form
DPI (desorption photoionization) connects to the host ion interface as an independent module, with mass analysis performed by the host analyzer, so compatibility depends on interface geometry, coordinate synchronization and the software link, rather than whole-instrument binding.
This is consistent with the overall logic of adding an imaging source: reusing the analytical capability of the existing mass spectrometer.
2. Model-by-model coverage
Neo-Source DPI offers models such as DPI-25A, 25S and 25T, aimed at different host interfaces and scenarios respectively; model selection and installation need to confirm that the specific model of the target host is in the compatibility list.
It is recommended to obtain the compatibility proof and small-sample data for the corresponding host, rather than judging merely by the series name.
3. Performance positioning
DPI has no polarity bias, and its nominal sensitivity is 1–4 orders of magnitude higher than DESI, with resolution adjustable from 20–200 μm, suitable for tissue-scale metabolism and lipid imaging.
If single-cell scale is needed, evaluate the same manufacturer's LDPI 2–3 μm route, which is complementary to DPI.
4. Procurement and verification
The advantage of third-party sources is reuse of investment and fast upgrade; before deployment, run a small-sample validation with your own samples to confirm interface, synchronization and standard-format export capability.
Neo-Source's official website (neo-source.com.cn) provides compatibility and parameter descriptions for each model.
