Markes receives accolade for Tandem Ionisation technology in analytical innovation awards

Markes International (Llantrisant, UK) has once more received an accolade for its electron ionisation technology for time-of-flight (TOF) GC–MS, coming third place in The Analytical Scientist Innovation Awards (TASIAs).
The award was given for its Tandem Ionisation® technology, which greatly speeds up the process of distinguishing between similar compounds and identifying unknowns, by allowing analysts to simultaneously acquire both reference-quality 70 eV spectra and repeatable ‘soft-ionisation’ spectra.
Providing these capabilities within a single GC run has the potential to change the way that analysts approach GC and GC×GC analyses – and is proving valuable for identifying long-chain alkanes in petrochemicals, and for discriminating between structurally similar terpenoids in fragranced products.
The award follows on from previous successes for Markes' related Select-eV® technology, which was widely recognised as one of the top analytical innovations of 2014.
Tandem Ionisation came third place in the latest awards, which are run by the industry magazine The Analytical Scientist, and judged by three independent experts in analytical science – Professor Hans-Gerd Janssen, Professor Robert Kennedy and Professor Emily Hilder.
Rich Whitworth, Editor of The Analytical Scientist, said “The Analytical Scientist Innovation Awards continue to showcase the instruments and technologies that we anticipate will have a game-changing impact on analytical science – and beyond. The 15 winners this year represent a diverse range of techniques and application areas, but all share something in common: a willingness to embrace creativity and invention to drive analytical science forward”.
The judges’ comments on Tandem Ionisation reflected the importance they attached to enhancing laboratory capabilities:
“All information needed for reliable compound information is contained in one run. Saves days of working and waiting time because it eliminates the need to re-configure complex GC–MS instruments.”
“Tandem Ionisation technology allows two different MS spectra to be collected simultaneously, which should greatly enhance the analyte identification capabilities of the technique.”
“Combining hard and soft ionisation offers unparalleled identification opportunities in GC.”
Dr Laura McGregor, Product Marketing Manager for Mass Spectrometry at Markes International, said “The development of Tandem Ionisation has been a significant project for the TOF MS team at Markes, and we’re delighted that this has been recognised in the form of a top place in this year’s TASIAs, especially considering the high standard of this year’s winners”.
Tandem Ionisation works by generating two sets of spectra from a single GC or GC×GC peak – 70 eV spectra for spectral matching against commercial libraries, and soft ionisation spectra for improved discrimination between structurally similar isomers and confirmation of the identity of ‘unknowns’. Crucially, acquisition of the soft ionisation spectra is not associated with the inherent loss of sensitivity historically associated with soft EI, and unlike other soft ionisation approaches does not require switching of ion sources or use of reagent gases.
The award comes after a string of successes in 2014 for Select-eV variable-energy ionisation, the technology on which Tandem Ionisation is founded. These included an ‘Honorable Mention’ at the Pittcon Editors’ Awards in March, a ‘Best of best’ at the ‘Canmol: Wales Marketing Awards’ in October, and fourth place in the TASIAs in December 2014.
