Wei et al., Anal. Methods, 2013, 5, 2440-2443

The latest issue of Analytical Methods is now available online. We have three beautiful covers featuring the most recent advances in the field of applied analytical chemistry.

Our outside front cover showcases the work of Xing-Jiu Huang and colleagues at the Chinese Academy of Sciences. The researchers introduce a new method to identify and quantify chlorobenzene micropollutants that are present in the natural environment. These pollutants have poor electrochemical activity and have been difficult to identify with electrochemical sensors. In this work, a novel ionic liquid–carbon nanotube composite sensor based on electrochemical impendance technique is proposed as an efficient sensor for micropollutants with poor electrochemical activity.

Wolf and Reagen, Alnal. Methods, 2013, 5, 2444-2454

The wonderful inside front cover of this issue features the paper of Susan Wolf and William Reagen from the Environmental Laboratory 3M Centre, St. Paul, USA. In the study, the authors report a novel analytical method for analysis of perfluorinated compounds in water. In particular, they optimise and validate a technique based on pre-sampling isotope dilution-direct injection-liquid chromatography tandem mass spectrometry (DI-LC/MS/MS).

Finally, the outside back cover of Issue 10 shows the research study of Zongxiu Nie and co-workers at the Chinese Academy of Sciences. In their work, the researchers present the rapid and direct detection of polyhydroxylated alkaloids in mulberry using leaf spray mass spectrometry and propose the leaf spray method for the rapid screening of lead compounds from natural plants during drug development.

Welcome to the latest issue of Analytical Methods!

We have a great new cover and a couple of HOT papers free for you to enjoy for the next four weeks. The outside front cover of this issue showcases the work of Monica Yang from Merck & Co., Inc. USA and colleagues at Eksigent, USA.

In their paper, the researchers present a liquid chromatography instrument for fast HPLC analysis, which provides good separation efficiency and system reproducibility. This system can be used efficiently for pharmaceutical analysis. Indeed, more than a dozen pharmaceutical components and related process impurities were resolved in 10 minutes on the micro LC instrument.

The latest issue of Analytical Methods is now available online. Take a look at our great new cover and read all about the innovative research behind it.

Stephen O’Driscoll and colleagues at the Dublin City University, Ireland, describe how we can use a simple mobile phone for environmental and diagnostic monitoring.

In their work featured in our outside front cover, they describe a phone’s camera which enables detection of fluorescence from a number of sensor spots on a disposable optical sensor chip without the need for communication with a remote server. The new method combines the functionality of the camera with the phone’s data processing and allows analysis of detected fluorescence intensity. According to the authors, mobile phones could represent an attractive technology platform for the development of portable sensors.
