MOBILion Systems has introduced a beta version of its first ion mobility separations product, which is based on Structures for Lossless Ion Manipulation (SLIM™). The SLIM technology was invented by Dr Richard Smith and has been licenced exclusively to MOBILion Systems. SLIM provides rapid, high-resolution separations in the gas phase on printed circuit boards, effectively digitising separations prior to mass spectrometry analysis. A 13-m serpentine ion path length can be achieved in a component that is 14 × 18 inches. The new product can be integrated with LC-MS workflows and can, for some applications, replace LC.
