The EconoPrep® is designed specifically to automate the difficult, error prone, labor intensive manual processes involved in sample prep for trace analysis. The EconoPrep offers economically priced consumable kits for Environmental and Food Matrices. The system uses reduced solvent making it a green alternative to manual techniques. It automatically performs Extraction, Sample Cleanup and Concentration allowing for same day results. More information Please link to this document and require a form to be filled out.

Environmental sample analysis by large-volume injection (LVI) in combination with liquid chromatography–tandem mass spectrometry (LC–MS-MS) is described for polar and nonpolar analytes in both aqueous samples and organic extracts.

Unexpected results from calibration standards create confusion in a clinical liquid chromatography (LC) method.

The 31st Montreux Symposium on LC–MS and MS–MS will be hosted by the International Association of Environmental Analytical Chemistry (IAEAC) at the Aldershof Convention & Exhibition Centre, Berlin?Aldershof, Germany, on 4–6 November 2015.

Recently, I received an inquiry from a reader regarding a problem he encountered with a routine liquid chromatography (LC) method in his clinical laboratory.

When Professor Georges Guiochon passed away last October, at the age of 83, the separation science community mourned the loss of one of the great pioneers of the field.

All sample preparation adds the potential for error to the analytical protocol, so choosing less-complicated techniques will help to reduce inherent error.

Here we describe a simple and robust high performance liquid chromatography–diode array detection (HPLC–DAD) method for the simultaneous determination of methotrexate (MTX) and sulphasalazine (SSZ) from plasma. MTX and SSZ are used in combination for the treatment of rheumatoid arthritis. Using two detector wavelengths, 304 nm for MTX and 358 nm for SSZ, we were able to selectively quantitate both analytes during the same chromatographic run. The method was validated using quality control samples for critical analytical performance criteria of recovery, reproducibility, selectivity, accuracy, and precision.

The LC/GC Checker app is designed to provide four approaches to check an LC or GC instrument's performance.

Selected dietary supplements labelled to contain Acacia rigidula have been found to be adulterated with the amphetamine isomer ?-methylphenylethylamine (BMPEA).

A new study presents a proteomics approach to investigate changes at the molecular scale that could control whether or not embyro implantation using IVF is successful.

Researchers from the University of Colorado have characterized flow?back water generated from fracking activities, using a combination of analytical techniques, to determine how best to treat wastewater so that it can be recycled.

Miniaturization has been one of the biggest trends in recent years. This article discusses the evolution and current applications of lab?on-a-chip technology in chromatography and explores the possibility of a new market for microfluidics in separation science.

Dr Vera Thoss from Bangor University (Bangor, Wales) spoke to Bethany Degg of The Column about her work investigating the chemistry of plants and the value of flash chromatography in this area of research.

Selected highlights of new products launched at Pittcon 2015.

Incognito offers his views on Pittcon 2015. What were your experiences like and did you have any arguments?

Since the founding of LCGC in 1983, we have made it our mission to serve the separation science community by publishing articles with a practical focus on improving chromatographic methods. Over the years, those articles have included many seminal works from leading analytical scientists who have made groundbreaking advances that have benefitted the entire community. This year, we are once again pleased to honour an outstanding chromatographer: Caroline West, the winner of the 2015 Emerging Leader in Chromatography Award. This year, we had the additional opportunity to honour West at Pittcon 2015 in an oral symposium as part of the Pittcon technical programme.
