Topics that stood out at HPLC 2018 include advances in large-molecule separations, multidimensional separations, 3D printing, chiral separations, and HILIC. Also, many speakers addressed separation fundamentals, including ways to increase speed, generate higher throughput, and add selectivity.

Many LC users are unclear what happens when we combine two (or more) flow streams in LC systems, and when mixers are needed to blend the fluids. This discussion explains why mixers are needed, and when and how you might consider using something other than the default mixer setting.

Modern trends in LC mobile-phase selection and preparation include using simpler mobile phases, increased use of MS-compatible mobile phases, and eliminating filtration and certain mobile-phase additives. Here, we discuss those and other trends and best practices, as well as the fundamentals behind them.
