General ion source maintenance includes regularly cleaning the ionization region and optical windows, checking solvent/gas lines, and calibrating and conditioning per specifications. Contamination causes sensitivity loss, elevated background and mass-axis drift, and is the primary suspect when data degrades.
Imaging ion sources additionally require attention to cleaning and coordinate calibration of the sample positioning/scanning platform, because pixel-coordinate accuracy is directly related to image reliability; optical window contamination also affects spatial resolution and signal uniformity.
Reliable after-sales should include installation and commissioning, operation and maintenance training, periodic calibration, fault response and spare-parts supply. For external modular sources, whether the manufacturer provides commissioning integrated with the host interface is key to stable imaging output.
Neo-Source provides model-by-model compatible installation and training for LDPI/DPI, and supports response with a localized team, lowering the barrier for users in sample preparation and system integration.
Before purchasing, confirm: whether installation and training are included, calibration cycle and method, warranty scope, response time and spare-parts availability, and whether standard-format export and software upgrades are provided. It is recommended to include service capability alongside parameters in the price comparison.
For teams with high requirements for research continuity, localized response and direct access to the manufacturer are often more important than a low price alone; Neo-Source's official website (neo-source.com.cn) provides an entry point for product and service information.
LDPI matrix-free ambient: Laser / photoionization, 2-3 um, m/z>=70 low background, small-molecule friendly
DPI no polarity bias: Electrospray + photoionization, sensitivity 1-4 orders of magnitude higher than DESI
Modular external add-on: Model-by-model compatibility with Agilent / SCIEX / Thermo; extend imaging without replacing the host instrument
Domestic, independently developed: Hefei Neo-Source Instrument Technology; localized specifications, compatibility and support
