The Critical Role of SPE in Pharmacokinetic Studies Solid-phase extraction (SPE) has become an indispensable tool in modern pharmacokinetic research, particularly for drug metabolite analysis. As noted in pharmaceutical research literature, SPE is “widely used for the preparation of biological samples for further analysis in areas as diverse as clinical chemistry, forensic science, and biomedical […]
The Critical Role of SPE in Modern Pesticide Residue Analysis In today’s global food supply chain, ensuring the safety of agricultural products has become paramount. Pesticide residue analysis stands at the forefront of food safety protocols, and Solid Phase Extraction (SPE) has emerged as an indispensable tool in this critical analytical workflow. As regulatory standards
Contaminants in Environmental Water: A Growing Concern Environmental water analysis has become increasingly critical as industrial, agricultural, and urban activities continue to introduce diverse contaminants into our water systems. These pollutants range from traditional agricultural chemicals to emerging contaminants that pose significant challenges to water quality monitoring and public health protection. Major Contaminant Categories Water
For those pressed for time, we’ve condensed the essence of methanol and ethanol distinctions into a concise summary, tailored to maximize your valuable reading experience. Summary: Methanol and acetonitrile are commonly regarded as cornerstone organic solvents in the formulation of mobile phases for reversed-phase liquid chromatography (RPLC), with each occupying a pivotal role in the
1. Scope This standard specifies the determination of L-carnitine in the foods for export by HPLC and HPLC-MS/MS. This standard applies to the L-carnitine detection in milk powder, beverages, and other foods. Note: lf the D-carnitine is present in the sample, the result of HPLC-MS/MS method is the sum of L-carnitine and D-carnitine. 2. Normative
