When you need to extract the maximum amount of information from a diverse range of compounds, you require the ultimate in ionization flexibility and performance.

Providing the highest performance without compromise, Waters range of mass spectrometry ionization source options are quick and easy to interchange, enabling the widest range of ionization techniques to be utilized universally across multiple analytical platforms.


The Atmospheric Solids Analysis Probe is a useful tool for the rapid direct analysis of volatile and semi-volatile solid and liquid samples using atmospheric pressure ionisation.

Obtain chemical information directly from a wide range of surfaces with Desorption Electrospray Ionization (DESI) mass spectrometry imaging with DESI XS.

The ionKey/MS System integrates the microflow UPLC separation directly into the source of the mass spectrometer with the iKey for unprecedented LC-MS system performance and sensitivity.

APCI is an effective method for analyzing lower-polarity compounds. The high-efficiency IonSABRE APCI probe offers significant improvements in sensitivity compared with earlier versions of probe, particularly at higher liquid flow rates.

The LockSpray dual electrospray ion source optimizes the co-introduction of analyte and lock mass compound directly into the ion source, providing authenticated exact mass measurement in MS and MS/MS modes.

The NanoLockSpray dual electrospray ion source accessory with optimized co-introduction of analyte and lock mass compounds provides authenticated exact mass measurement in NanoFlow LC-MS and LC-MS/MS modes of operation.

The UniSpray ion source enables ionization of a wider range of analytes in a single run, allowing you to spend less time changing sources and more time analyzing samples.

Excellent ionization efficiency and high sensitivity with Atmospheric Pressure Gas Chromatography (APGC), a soft ionization technique that is convenient to use and can be quickly swapped out to LC when desired.
