Frequently Asked Questions
Does SPion™ work?
Yes, it works. The technology is based on the stacked-ring ion guiding principle. If you are interested in learning more about ion guiding with RF, please see: Gerlich, Dieter. "Inhomogeneous RF fields: A versatile tool for the study of processes with slow ions." State-Selected and State-to-State Ion-Molecule Reaction Dynamics. Part 1: Experiment 82 (1992).
How efficient is SPion™ in transferring the ions?
High-efficiency ion transfer is one of the key features of SPion™. The potential well created by RF electric fields maintains ions on the centeral axis of SPion Tube™.

State-Selected and State-to-State Ion-Molecule Reaction Dynamics. Part 1: Experiment 82 (1992).
How long can SPion™ be?
Pretty long. SPion Tube™ transfers ions with high efficiency across relatively long distances -at this point, at least several meters.
Does bending SPion™ affect ion transfer?
No, curvature does not affect ion transfer efficiency. Obviously, extreme bending will damage SPion.
Is SPion™ able to be fitted to all makes and models of mass spectrometry systems?
SPion™ can be interface with mass spectrometry system with atmospheric pressure sampling inlet. Depending on the make and model of your mass spectrometer, interfacing SPion to your system will require engineering work.
What type of ion sources can I use with SPion™?
Any type of ambient ionization source may be used with SPion™.
Is SPion™ patent protected?
Yes, we have few pending patent applications. You can check them out here.
Are there any publications related to SPion?
We will be presenting the results from SPion technology at the 68th ASMS Conference on Mass Spectrometry and Allied Topics (ASMS) 2020 in Houston, TX. More application notes and publications will follow. Please sign up to stay updated.
Can I treat SPion™ like a regular tube?
Although SPion™ Tube looks like a regular tube, it is actually a very delicate piece of mass spectrometry instrumentation. SPion has been tested to endure significant bending, but can be subject to damage with misuse like any other piece of instrumentation.
Is SPion™ a medical device?
No, SPion™ is intended and marketed solely for use in research settings. SPion™ is neither offered, marketed, nor intended for use as a “medical device,” as defined by the U.S. Food and Drug Administration’s regulations. SPion™ is not intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease, in man or animals.
Does SPion™ offer ion mobility separation?
SPion™ 1st Gen does not offer ion mobility separation.
How flexible is SPion™?
SPion™ is very flexible, having a working bend radius of 10cm.
Does SPion™ expose me or my samples to any high voltage?
