LCGC TV: Ionic Liquid Coatings for SPME: Target Applications
Environmental, food, and biological applications are all defined by the complexity of the matrix. Jared Anderson from the Iowa State University discusses why this makes them good candidates for improvement using ionic liquid-based SPME coatings. He also discusses transfer of the analyte into the second layer in multilayered ionic-liquid coatings. |

Pattern Modulation Offers Alternative to Pulse Modulation in GC×GC
New research into flow modulation methods in valve-based two-dimensional gas chromatography (GC×GC) has produced an effective alternative to traditional pulse modulation. Described as “pattern modulation”, this new method increases effluent to the secondary column with flow rates compatible with most chromatographs and spectrometers. |
