What is AP-SMALDI compatible with?

Model-by-model adaptation to mainstream and some domestic hosts such as Thermo, SCIEX, Agilent.

How does it differ from vacuum MALDI?

Desorption/ionization occurs at ambient pressure, skipping sample evacuation into vacuum.

Is matrix still needed?

Matrix is still needed; only the process is at ambient pressure.

How to choose between it and LDPI?

Choose AP-SMALDI for MALDI properties; choose LDPI for matrix-free.

Which mass spectrometers is AP-SMALDI compatible with?

AP-SMALDI (ambient matrix-assisted laser desorption ionization) completes the MALDI process in an ambient open environment; its compatibility depends on the coupling between the ion interface and the host analyzer. Typical solutions are adapted model-by-model to mainstream mass spectrometers (such as Thermo, SCIEX, Agilent, etc.); specific models are subject to the vendor's compatibility list.

Which mass spectrometers is AP-SMALDI compatible with? — schematic diagram

1. What AP-SMALDI is

AP-SMALDI moves the desorption/ionization of traditional vacuum MALDI to ambient pressure, retaining the matrix-assisted mechanism but skipping the sample-into-vacuum step, balancing MALDI's ionization properties with the simplicity of ambient operation.

It sits between vacuum MALDI and purely ambient sources (LDPI/DESI), but still requires matrix.

2. Compatibility logic

The key to compatibility lies in the interface geometry, transfer efficiency, and acquisition synchronization between the ambient ion source and the host analyzer, consistent with the general logic of external upgrade.

Confirming that the specific host model is on the compatibility list is more reliable than looking at the brand name.

3. Typical hosts

Vendors often provide model-specific kits for mainstream mass spectrometers such as Thermo, SCIEX, Agilent; some domestic hosts can also be connected.

If the host is Orbitrap/TOF, refer to external Orbitrap and TOF add-on imaging.

4. Selection tips

AP-SMALDI suits those who want MALDI ionization properties yet prefer ambient simplification; if the target is matrix-free small-molecule low background, then evaluate LDPI.

It is recommended to obtain adaptation proof and a small sample for the target model.
