Why Multi-Residue Pesticide Screening Demands High Throughput Regulatory bodies such as the EPA and EFSA require monitoring of hundreds of pesticides in food and environmental samples. Traditional single-cartridge solid-phase extraction (SPE) methods struggle to keep pace with the volume of samples, creating a bottleneck in laboratories. High-throughput methods are essential to meet compliance deadlines and […]

The Growing Need for High-Throughput Biomarker Testing Clinical biomarker analysis is foundational to modern diagnostics, drug development, and personalized medicine. With the rise of large-scale clinical trials and population screening programs, laboratories face increasing pressure to process hundreds to thousands of samples daily while maintaining high data quality. Traditional solid-phase extraction (SPE) using individual cartridges

Introduction to Drug Metabolite Analysis In pharmaceutical development, drug metabolism studies are critical for understanding the absorption, distribution, metabolism, and excretion (ADME) properties of new chemical entities. Metabolite identification and quantification help predict pharmacokinetics, potential toxicity, and drug-drug interactions. Regulatory agencies like the FDA require comprehensive metabolite profiling during preclinical and clinical phases, making robust

Introduction to Metabolomics in Systems Biology Metabolomics, the comprehensive study of small-molecule metabolites within biological systems, plays a pivotal role in systems biology research. It provides a functional readout of cellular activity, reflecting genetic, epigenetic, and environmental influences. By profiling endogenous metabolites such as amino acids, lipids, organic acids, and nucleotides, researchers can uncover biomarkers

Drug Discovery Workflow Overview The drug discovery pipeline is a complex, multi-stage process that begins with target identification and validation, followed by hit discovery, lead optimization, preclinical testing, and clinical trials. Throughout these stages, scientists generate thousands of samples that require robust analysis to identify promising candidates. Bioanalytical support is critical for pharmacokinetic (PK), pharmacodynamic

Overview of SPE Cartridge Format Solid-phase extraction cartridges represent the traditional format that has been in use for over two decades. These syringe-barrel style devices typically contain sorbent masses ranging from 10 mg to 6 g, housed in plastic or glass barrels with polymer or steel frits. The cartridge format offers several distinct advantages for

Challenges in High-Throughput Analytical Testing High-throughput laboratories face significant challenges in maintaining analytical efficiency while processing large sample volumes. As noted in the literature, “sample preparation is the rate-limiting step for many analyses” (Simpson, 2000). With modern analytical instruments like LC-MS/MS operating with run times of just 2-3 minutes, laboratories often experience backlogs in sample
