A review of the trends at this year's symposium, including discussions of column technology, sample preparation, and detector usage.

A review of the advances and trends in technology and applications discussed at the HPLC 2013 conference, including a summary of the awards presented.

Part 1 of evidence to demystify HPLC and UHPLC column myths

A summary of the results from a survey of 14 leading HPLC–UHPLC column experts is presented, covering the state of sub-2-?m porous particles, superficially porous (core–shell) particles, silica monoliths, and polymeric monoliths.

Evidence to demystify HPLC and UHPLC column myths

For the next improvements, we must look beyond the column.

Part I of Ron Major's report on new products introduced at Pittson. This month, columns are highlighted, covering all modes of high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), and liquid-phase separations.

This month's installment of "Column Watch" comprises Part II of our yearly report on new products introduced at Pittcon. Gas chromatography columns, sample preparation products, and hardware, accessories, and small tabletop instruments mainly for sample preparation are covered.

A brief introduction to this special supplement by Guest Editor Ron Majors

Part I of our yearly report, covering columns for all modes of HPLC, UHPLC, and liquid-phase separations.

This article discusses the details of how the newer techniques of sample prepaation are simplified by the use of LC–MS–MS and GC–MS–MS technology.

This short review covers the use of ionic liquids (ILs) and polymeric ionic liquids (PILs) in solid-phase microextraction (SPME) and dispersive microextraction (DLLME)

Howard G. Barth and Ronald E. Majors Liquid–solid extraction is the most popular method, but sometimes modern approaches such as PLE/ASE and MAE are possible.

This instalment focuses on approaches and techniques for extracting and concentrating small molecules of interest present in polymeric materials.

This article discusses the details of how the newer techniques of sample preparation are simplified by the use of LC–MS-MS and GC–MS-MS technology.

By achieving selectivity in other portions of the analytical cycle, we can lower the burden on sample preparation.

A review of the trends at this year&s symposium, including discussions of column technology, sample preparation, and detector usage.

Annual review of the HPLC conference.

This article provides examples of the use of SLE, demonstrates some of its advantages and provides commercial sources for SLE products.

An alternative approach to liquid–liquid extraction is explored.

This month's "Sample Prepartion Perspectives" describes practical aspects of hollow-fibre liquid-phase microextraction in the three phase mode (HF3LPME) and also electromembrane extraction (EME), which uses an electrical potential as the driving force for the extraction.
