Electrophoresis is a very useful separation method employed in a great variety of applications, including the separation and analysis of biological samples (e.g. DNA and proteins) and environmental samples (e.g. pesticide or pollutant analysis).  Electrophoresis comes in various different forms (capillary or gel electrophoresis for example) making it a very versatile and adaptable technique.

Analytical Methods presents an excellent forum for advances and applications of this technique, and below is a sample of the high-quality work we have published in this area.  These articles are free to access until the 13th February 2012 so make the most of this and take a look!

Analysis of food and agricultural products or materials is a very topical subject at present.  Development of sensitive, accurate and versatile analytical methods are important in order to monitor food and agricultural standards, understand the composition or structure of food, and to detect levels of toxic or unwanted chemicals.  Recent examples include monitoring levels of melamine in milk or pesticide residues in food.

Analytical Methods presents an excellent forum for such work, and below is a sample of the high-quality work we have published in this area.  These articles are free to access until the 13th January 2012 so make the most of this and take a look!
