Chemical Profile of Organic Acids in Bioanalysis Organic acids represent a diverse class of compounds that play crucial roles in biological systems, including metabolic intermediates, signaling molecules, and biomarkers of disease states. In bioanalysis, these compounds typically feature carboxylic acid functional groups with pKa values ranging from 2-8, classifying them as weak acids. Common examples […]

Environmental Concern of Perchlorate Contamination Perchlorate contamination in drinking water has emerged as a significant environmental and public health concern over the past two decades. Perchlorate (ClO4–) is a highly soluble and stable anion that originates primarily from industrial activities, particularly the manufacture and use of rocket propellants, fireworks, and explosives. Unlike many other contaminants,

Chemistry of Acidic Analytes Acidic analytes represent a broad class of compounds characterized by their ability to donate protons, typically containing functional groups such as carboxylic acids, phenols, sulfonic acids, or phosphonic acids. These compounds exhibit unique chemical behavior that directly impacts their interaction with solid-phase extraction (SPE) sorbents. Understanding their fundamental properties is crucial
