Kore Technology is one of very few companies still willing to design and manufacture custom Time-of-Flight Mass Spectrometry (TOF-MS) systems. When considering adding a TOF-MS to existing experimental equipment, our clients start by explaining to the Kore team what analytical measurements they wish to achieve. Our team of physicists, chemists and electronics/mechanical engineers thrives on the challenge of providing these one-off, customised solutions.
For our clients in 2025, we redesigned our Add-On TOF product range to offer:
- 18mm Dual Micro Channel Plate (rather than discrete dynode) detector
- Software-controlled power supply and data acquisition
- Reconfigurable and variable length ion optics for custom applications
- Operation at 120V and 240V
- Analogue and digital ion-counting systems
- Data outputs to integrate with various client software
- Pressure-defining apertures to operate in a variety of pressure regimes
This year, our Add-On TOF clients have challenged us in many state-of-the-art applications, including identification of combustion products in a molecular beam via skimmer cone; purification of short-half-life medical isotopes; energetic materials isotope purification for battery technology; laser-ionization of neutral atomic beams; characterisation of electrospray ion beam deposition; and integration with atomic vapour deposition equipment for metallurgy research.
The Add-On TOF can be configured with or without an electron impact ion source prior to the ion optics. The ion detection system can either be a digital pulse counting system, or an analogue counting system, depending on the nature of the experiments. Our team is very happy to advise.
Our enhanced client support comes as standard, as anyone who’s ever bought a Kore instrument will attest – no problem is unresolvable. We support our users and their instruments long-term, with some Kore instruments in daily use 20 years after delivery! Our knowledgeable team can provide spare parts and maintenance agreements to support you and your system.
As we look ahead to the year-end festivities, it’s time to sing the praises of the Kore Add-On TOF, our 2025 bestseller.
While most manufacturers converge on standardised analytical products, Kore Technology remains a rare find, helping unique world-class scientists to achieve unprecedented measurement goals.
The Kore team extends thanks to all our Add-On TOF clients (see recent publications list).
