Originating from a collaboration of MCS members with the team of Gert Desmet and Wim De Malsche of the Department of Chemical Engineering at the Free University of Brussels, a paper entitled "Chip-Based Multicapillary Column with Maximal Interconnectivity to Combine Maximum Efficiency and Maximum Loadability" was published in the ACS journal Analytical Chemistry.
Following previous work on pillar array columns for liquid chromatography, a new pillar array design is reported that renders high-efficiency, high volumetric loadability gas chromatography columns. The proposed column configuration contains a perfectly order packed bed that can also be seen as a multicapillary column with 8 parallel tracks with maximal interconnectivity between the flow paths. Obtained plate numbers efficiencies are in the range 12,500 - 60,000. The full paper can be found at this DOI: 10.1021/acs.analchem.7b03036
