Introduction Hexane extractable material (HEM), also known as Oil & Grease extraction is a simple water quality measurement. The measurement can be used to assess pollution for compliance or as a meas...
Executive summary Peptides have garnered much attention in a variety of applications over the last few years, and interest only continues to grow. With improved synthetic strategies, peptides are now ...
You analyze a lot of biological samples. You deliver accurate, reliable data, consistently. You use sophisticated, high-end analytical techniques such as LC-MS/MS or GC-MS. And the pressure is always ...
Part I: Principles of evaporation Evaporation is a process used to concentrate samples by vaporizing and removing liquid solvents, leaving behind the dissolved solid components. Evaporation is essenti...
The main purpose of sample preparation is to extract the target analyte(s) from the sample matrix, allowing them to be measured by the chosen analytical technique, such as LC-MS/MS or GC-MS. This can ...
Introduction Discovering new chemical entities (NCEs) or new molecular entities (NMEs) is costly and time consuming. One needs only to look at the top 15 global pharmaceutical companies to see how exp...
Introduction As environmentally responsible chemists we all want to reduce the chemical waste volume we generate in our daily research activities. While the chemicals we use are necessary for what we ...
Figure 1. Structure of Acrylamide. Introduction Acrylamide is a small polar highly water soluble molecule formed when carbohydrate rich foodstuffs are cooked at high temperatures. Acrylamide was first...
Chemical synthesis has been around for a long time - Hermann Kolbe first used the term ‘synthesis’ in the way in which modern chemists understand it in the 19th century1. Many of the important named r...
Introduction The diverse nature of the samples in food safety testing applications adds complexity making method standardisation challenging. However, default methodology for solid matrix pesticide an...
