New data from our ABR breakthrough analyzer!

A recent publication in the Journal of the American Chemical Society featured data measured on the new Hiden Isochema ABR breakthrough analyzer.

Professor Andy Cooper and his group at the University of Liverpool, together with collaborators from Imperial College London and Queen’s University Belfast, reported the use of porous organic cages for the separation of sulfur hexafluoride from nitrogen [1].

Single crystal diffraction experiments were performed at the Diamond Light Source in Didcot, near Oxford, UK, together with laboratory powder X-ray diffraction and in-situ powder diffraction at Diamond, for characterization purposes. Computer simulations were also carried out to analyze SF6 diffusion in one of the materials, CC3, which was subsequently tested experimentally in an ABR analyzer equipped with a Hiden Analytical quadrupole mass spectrometer.

Breakthrough curves were measured at 293 K and ambient pressure, with an industrially relevant 90%/10% mixture of N2/SF6. The data clearly demonstrates the separation capability of this material. The SF6 was also efficiently desorbed using a helium purge gas stream.

Further details can be found in the publication, which can be downloaded from the ACS website. For further information regarding Hiden Isochema’s range of breakthrough analyzers, please contact us.
