SPE Troubleshooting

What Causes Channeling in SPE Cartridges Channeling in solid phase extraction (SPE) cartridges represents one of the most significant flow problems that can compromise extraction efficiency and analyte recovery. According to established literature, channeling occurs when liquids take the path of least resistance through the sorbent bed, creating tunnels or channels that bypass the majority

Breakthrough Due to Low Sorbent Capacity Breakthrough is the ineffective retention of target analytes on the solid phase sorbent, resulting in low analyte recovery. This occurs when the analyte passes through the column unretained during loading or wash phases. The most common cause of breakthrough during sample application is flow rates that exceed the sorbent

What is Channeling in SPE Cartridges? Channeling in solid phase extraction (SPE) cartridges refers to the formation of tunnels or pathways through the sorbent bed where liquids flow preferentially, bypassing the majority of the stationary phase. This phenomenon occurs when excessive vacuum or pressure is applied during conditioning or sample loading steps, causing liquids to

Understanding SPE Breakthrough: The Critical Phenomenon in Solid-Phase Extraction Solid-phase extraction (SPE) breakthrough represents one of the most significant challenges in analytical sample preparation, directly impacting method accuracy, precision, and overall analytical performance. As product manager at Poseidon Scientific, I’ve witnessed how breakthrough issues can compromise entire analytical workflows, leading to false negatives, inaccurate quantitation,

Common Causes of Low Recovery in SPE Low recovery in solid phase extraction (SPE) is one of the most frustrating challenges analytical chemists face. When your target analytes fail to appear in expected concentrations, it’s essential to systematically identify where the problem lies. According to forensic science literature, recovery problems in SPE can be categorized

Understanding the Critical Factors in SPE Reproducibility Solid Phase Extraction (SPE) has revolutionized sample preparation across forensic, clinical, and environmental laboratories, offering significant advantages over traditional liquid-liquid extraction methods. As noted in forensic applications, SPE has been shown to significantly increase gas (GC) and liquid chromatography (LC) column life while reducing downtime on sensitive instruments

Sources of Particulate Contamination in SPE Cartridges Particulate contamination represents one of the most common and frustrating challenges in solid-phase extraction workflows. As an experienced product manager at Poseidon Scientific, I’ve seen firsthand how particulate matter can compromise SPE cartridge performance, leading to clogging, reduced flow rates, and inconsistent recoveries. Environmental samples frequently contain a

Understanding SPE Recovery Challenges Solid Phase Extraction (SPE) has revolutionized sample preparation across analytical laboratories, offering significant advantages over traditional liquid-liquid extraction methods. However, achieving consistent, high recovery rates (ideally exceeding 90%) can sometimes prove challenging. As a product manager at Poseidon Scientific specializing in SPE products, I’ve encountered numerous scenarios where recovery issues arise.
