Sterols are lipids in our bodies that help maintain the integrity of cell membranes and are transported by lipoproteins in the bloodstream. They exist as free sterols and steryl esters (sterols combin...
Evaporation is a key step in the sample preparation workflow, either to concentrate analyte of interest or to exchange a solvent for one more compatible with the subsequent analytical technique. Sampl...
Pesticide residues in food, even at low levels, pose significant health risks and have been linked to chronic illnesses and developmental issues. To protect consumers, regulatory authorities closely m...
Extractable Petroleum Hydrocarbons (EPH) may be invisible, but their impact on the environment is tangible. Through advanced monitoring techniques and a robust regulatory framework, we strive to strik...
In the world of science, there are always new topics and compounds that are discovered, but not all of them get much publicity. One of these is acrylamide. Now you’re probably saying to yourself, “wha...
Often the question arises asking how can I extract both acids and bases with the same Supported Liquid Extraction (SLE) procedure. Is this possible? And how?
Unbiased peptide screening technologies have evolved, improved and recently gained acceptance by the community as strategies for identifying new lead compounds against old targets with in novel chemic...
Preparative HPLC and flash chromatography are two of the most utilized techniques for purifying molecules post synthesis. To monitor sample purity and elution times, detection techniques such as UV/UV...
Evaporative light-scattering detection (ELSD) is an effective tool for detecting compounds with minimal to no UV absorbance. ELS detectors convert the column effluent into an aerosol by adding heated ...
