Laboratory Techniques

Sample Preparation Before Loading Proper sample preparation is the foundation of successful solid-phase extraction (SPE). Before loading your sample onto an SPE cartridge, several critical factors must be addressed to ensure optimal analyte recovery and minimize interferences. The sample matrix can significantly impact SPE performance, particularly when dealing with viscous samples or those containing particulates,

Proper Storage Conditions for SPE Cartridges As a product manager at Poseidon Scientific with extensive experience in SPE technology, I can confidently state that proper storage conditions are fundamental to maintaining the performance and reliability of SPE cartridges. Based on comprehensive research and manufacturing standards, SPE cartridges should be stored under specific environmental conditions to

Sources of Contamination in SPE Workflows Solid Phase Extraction (SPE) contamination problems can arise from multiple sources, compromising analytical accuracy and reproducibility. According to forensic science literature, contamination issues are categorized alongside flow problems, recovery problems, and nonextraction problems as fundamental SPE troubleshooting areas. SPE Device-Related Contamination The most common contamination sources directly attributable to

The Critical Importance of Proper SPE Cartridge Conditioning Solid Phase Extraction (SPE) cartridge conditioning is the foundational step that determines the success or failure of your entire extraction process. As Dr. Xu, product manager at Poseidon Scientific, I’ve seen firsthand how proper conditioning techniques can dramatically improve recovery rates, precision, and overall method reliability. SPE
