Ionicon - Model APi-TOF -Atmospheric Pressure Interface Time-of-Flight
Atmospheric Pressure Interface Time-of-Flight (APi-TOF) Instrument for Detection of Positive or Negative Ions based on the ioniTOF platform and Hexapole ION-GUIDES. The IONICON ioniAPi-TOF is a modular and robust Time-of-Flight mass spectrometer designed for the detection and mass analysis of ions generated at atmospheric pressure. The ioniAPi-TOF atmospheric pressure interface consists of a critical orifice for contact free sample introduction, two hexapole ION-GUIDEs for high ion transmission efficiency over a broad m/z range and a high performance pump for high sample throughput. This interface is coupled to an orthogonal TOF analyzer equipped with an ion mirror for increased mass resolution. Our next generation TOF power supplies allow fast and repeatable switching between positive and negative polarity.
The new APi-TOF platform is a very attractive instrument for gaining new insights in science, enabling:
- a broader detectable m/z range than established designs,
- fast (less than 10 s) switching between positive and negative polarity
- low energy ion transfer for decreased ion-chemistry artefacts
- modular mass resolution thanks to the ioniTOF platform
These benefits are exclusive features of the ioniAPi-TOF. Contact us for a quote!
Flexible front-end design
The front-end of the ioniAPi-TOF is simple and flexible in design for easy coupling of the ionization source of your choice, e.g.
- atmospheric pressure chemical ionization (APCI)
- electrospray ionization (ESI)
- electric discharge ionization like Corona discharge
- radioactive ionization like Americium-241
- X-ray ionization
- Photoionization
- or even galactic cosmic rays producing naturally charged atmospheric ions
The ioniAPi-TOF atmospheric pressure interface consists of a critical orifice for contact free sample introduction, two hexapole ION-GUIDEs for high ion transmission efficiency over a broad m/z range and a high performance pump for high sample throughput. This interface is coupled to an orthogonal TOF analyzer equipped with an ion mirror for increased mass resolution.
The advantage of the IONICON hexapole ION-GUIDE over conventional quadrupole interfaces is that the energy in the multipole is lower which decreases unwanted ion-chemistry artefacts. Another advantage is that the mass range that is transmitted through the multipole is much broader.
The ioniAPi-TOF is optionally available as a system where both polarities of the TOF-MS, positive and negative, are enabled in parallel. Therefore, there is no need to switch or sacrifice valuable data. Two virtually identical versions of this setup with opposite polarity are integrated in one compact instrument so that ions with both polarities can be detected simultaneously. Alternatively the user can operate both systems independently and benefit from a very advantageous offer for the ioniAPi-TOF set-up.
Another advantage is that the ioniTOF is designed as a modular and flexible TOF-MS platform that allows you to choose the mass resolving power you need and also upgrade to higher resolution if you feel the need at a later stage of your experiments. Discover the ioniTOF ecosystem!
