| At LECO’S GC×GC Workshop & Symposium, Paul Harvath gave a talk about "Evaluation of Oxidized Base Oils by Flow Modulated Two-Dimensional Gas Chromatography – Time of Flight Mass Spectrometry". In his talk he gave an insight about the history and future of engine oils for cars, and how the lubricants changed over the times. The talk outlined the challenges the industry is facing and explains how those challenges are being approached. Besides the introduction of the oil sample preparation, Paul Harvath compared the work with the LECO FLUX Flow Modulator with the traditional LECO Liquid Nitrogen based modulation and presents the benefits of both technologies. He also gave an insight into the vast advantages of GC×GC technology for his work which could be seen in the data evaluation. ### By viewing this presentation you will learn more about: - advantages in GC×GC and TOF technology compared to one dimensional gas chromatography - sample preparation - introduction of the flow modulation technology - importance of data quality. |
