Is Two-Dimensional LC Worth the Effort?
Two-dimensional liquid chromatography (2D LC) is a powerful technique, but method development is more involved and time-consuming. So for what types of analyses does it make sense to invest the extra effort to develop a 2D LC method instead of a 1D method? Dwight Stoll explains. More...

Beer Marinade Inhibits PAH Production
A team of scientists in Portugal and Spain have performed high performance liquid chromatography coupled with fluorescence detection (HPLC–FLD) to show that marinating pork meat in beer can reduce the levels of polycyclic aromatic hydrocarbons (PAHs) formed when grilled over charcoal. More...
Making Chromatography Data Manageable
The speed at which it is now possible to develop and run many chromatography methods is a great benefit to analytical chemists. The Chromatography Solution Center is here to help. The Solution Center, developed by LCGC in coordination with Thermo Scientific, can help you find answers to your analytical challenges by providing a variety of articles, application notes, videos, and other resources - updated monthly. Check out this month's installment of the Chromatography Data Systems (CDS) section.
Retention and Selectivity of Aromatic Hydrocarbons with Polar Groups in Ternary Reversed-Phase–HPLC Systems with Tetrahydrofuran as Modifier
The variation in selectivity of aromatic hydrocarbons with bisubstituted polar groups was investigated in systems comprised of a C18 stationary phase and ternary eluents. The ternary eluents were obtained by mixing binary solvents (organic modifier + water) of a similar eluent strength. Acetonitrile, methanol, and tetrahydrofuran were the organic modifiers applied. The influence of the organic solvent type on retention and selectivity of the solutes and its concentration in the ternary mobile phase is discussed. The approach previously presented by our group was adapted to explain the selectivity change. More...
The Essentials: Mixed-Mode HPLC Separations: What, Why, and How
In this excerpt from LCGC’s e-learning tutorial, the mechanisms of mixed-mode chromatography are explained, with reference to the parameters that are used to optimize selectivity and retention. More...

UHPLC Method Development and Modelling in the Framework of Quality by Design
The goals in ultrahigh-pressure liquid chromatography (UHPLC) method development are to first find the best separation, second find the best column, and third find the most robust method in a multifactorial Design Space. Trial and error methods are not sufficient anymore and solid science based on Quality by Design (QbD) principles is required. Control strategies and continual improvements of the methods are necessary, which offer much greater flexibility in the quality control laboratories than before. Modelling tools based on QbD principles used in method development give transparency to the control of multivariable influences and achieve faster drug applications and commercial authorization by the regulatory agencies.
