Choosing the correct column for an application really requires that we consider the many factors which can influence the efficiency and selectivity of a separation including column hardware, support and surface chemistry. On a rainy day a little while ago our technical support group came up with a list of 23 such factors which need to be considered.
Intertek (Texas, USA) has opened a new chemical laboratory to support the growth of the growing refining and petrochemical complex in Texas City (Texas, USA).
Porvair (Leatherhead, UK) has signed a technology licensing agreement with Thermo Electron Manufacturing, a division of Thermo Fisher Scientific (California, USA). Porvair has licensed its filter technology to Thermo to develop a range of life science sample preparation filters. Porvair will manufacture the products, and Thermo will distribute and market the products worldwide.
What would you do if faced with a zombie invasion in your analytical laboratory? LCGC Blog editor Kevin Schug provides guidelines and suggestions for fending off an attack, including how to use glassware and dead chromatography columns as defensive weapons and novel applications for laboratory lasers.
A novel orally active insecticidal peptide (OAIP-1) has been isolated from the venom of one of Australia's largest spiders, the Australian tarantula (Selenotypus plumipes) using reversed-phase liquid chromatography (reversed-phase LC) coupled with mass spectrometry (MS). The study was recently published in the journal PLOS ONE.1

The Urine Metabolome Database (UMDB) (www.urinemetabolome.ca) containing detailed information on over 3000 metabolites has been launched following the comprehensive quantitative metabolome characterization of urine by scientists at the University of Alberta, Canada.1 The project is part of the on-going Human Metabolome Project launched in 2005 by Genome Canada and Genome Alberta, and has so far received $600 million in funding from the Canadian government.
Environmental and pharmaceutical application, forensics, material and food production analyses – Shimadzu’s HS-20 headspace sampler serves GC and GCMS applications particularly in testing and inspection organizations.
Malvern Instruments (Malvern, UK) has acquired NanoSight (Amesbury, UK), a nanoparticle characterization company. The acquisition was completed on 27 September 2013.
Peak Scientific has recently opened an extension of their head office in Inchinnan, Scotland, named Cherry Tree House. The extension will accommodate the expansion of the company since it launched in 1997.

The experimental design that considers gradient time and temperature was expanded to include a third factor, either pH or ternary composition, and modelling software facilitated the analysis.
The parameters that should be considered in the optimization of HPLC methods are explained and then illustrated through the analysis of two commercial agricultural products.
Supercritical fluid chromatography has become a viable option for the separation scientist in diverse areas, and the field now seems more adequately described as an extension of HPLC, or perhaps as "carbon dioxide–based HPLC".
The authors explain modern UHPLC instrument design and outline simple procedures to identify causes of poor column and method performance.
When choosing the articles to include in this supplement, my selection was based on a very simple criterion.
