EPA Method 1664, Revision A describes the determination of oil and grease from liquid (typically water) samples.

This article describes modifications to US EPA Method 218.6 for detecting dissolved hexavalent chromium in drinking water, to permit a MDL of 0.001 µg/L

This article describes a 2D matrix elimination ion chromatography method to analyse samples containing high levels of matrix ions.

In this review, practical principles and guidelines for designing LC?LC methods are given.

A review of separations of chlorite, chlorate and bromate in water using ion chromatography and their determination.

The N-methylcarbamates and the N-methylcarbamoximes are among the most widely used pesticides in agriculture. Dionex has announced an improved HPLC method for the determination of these chemicals.

Discussing the latest developments in sample preparation techniques that reduce environmental impact.

The European Union has published new regulations regarding the approved testing methods for detecting marine biotoxins in bivalve molluscs, including oysters and mussels.

Thermo Fisher Scientific?s Global Food Safety Response Centre in Dreieich, Germany has announced that it is monitoring the dioxin crisis in Germany where animal feed additives may have been tainted with industrial fats containing the toxic chemical.

A novel and sensitive approach for analysing high-molecular-weight phthalates is described.

A method based on SPME and GC–MS was developed to analyse chlorophenols and their metabolites in aqueous samples.

A simple and rapid test for cobalt in leguminous plants has been developed that Spanish and Venezuelan chemists claim could provide an alternative to more expensive methods.

Following the accident at Chernobyl Nuclear Power Plant in 1986, the surrounding area remains substantially contaminated with radioactive isotopes. A study into the adaptations of the surrounding plant life has suggested that the plant proteomes remain largely unchanged by the radio contamination.

The development of a microfabricated comprehensive GC that can be used as a portable measurement device.

The Column spoke to Linde AG about how emissions are controlled and monitored to reduce the potentially harmful risks to the environment.

This article considers the key challenges faced within this changing arena and how environmental testing laboratories can strive to meet them.

Thermo Fisher Scientific has announced that its global Food Safety Response Centre in Dreieich, Germany, has developed two new analytical screening methods in response to the oil spill in the Gulf of Mexico.

Peas, beans and some other plant seeds contain proteins, called globulins, which have been shown to act as a defence against insects and other herbivores. Coffee beans contain large amounts of globulins, so scientists in Brazil studied the beans to assess their potential for warding off insects.
