The Impact of Column Hardware on Efficiency in Liquid Chromatography (LC)

Column hardware in liquid chromatography—that is, the tubing, the frits, and fitting—has a strong influence on separation performance or the reproducibility of chromatographic data. Flow distributors and frits can introduce serious band broadening when separation is performed in short, narrow-bore columns. The kinetic performances of packed and monolithic columns are usually similar for well-retained analytes. However, monolithic columns may show significantly better performance for early-eluting compounds, which can be attributed to the moderate mobile phase dispersion caused by the simpler column hardware because no frits are required.
