Sample preparation is often the most critical step in analytical chemistry. Even the most advanced LC-MS/MS or GC-MS system cannot compensate for poor sample cleanup. Among modern sample preparation techniques, Solid Phase Extraction (SPE) and QuEChERS are two of the most widely used approaches. Both improve analytical accuracy, reduce matrix...

Florisil vs Silica SPE Columns: Key Differences Selecting the appropriate Solid Phase Extraction (SPE) sorbent is one of the most important decisions in analytical sample preparation. Among normal-phase sorbents, Florisil SPE and Silica SPE are widely used for separating compounds based on polarity, removing matrix interferences, and improving analytical accuracy....

Solid Phase Extraction (SPE) is one of the most effective sample preparation techniques for improving analytical sensitivity, reducing matrix interference, and extending instrument lifetime. Whether performing pharmaceutical analysis, environmental monitoring, food safety testing, or clinical bioanalysis, a well-developed SPE method is essential for obtaining accurate and reproducible results. However, SPE...

Solid Phase Extraction (SPE) is one of the most widely used sample preparation techniques in analytical chemistry, helping laboratories improve analyte recovery, reduce matrix effects, and protect LC-MS and HPLC systems. Among the many SPE sorbents available, C18 SPE and HLB SPE are the two most frequently selected options. While...
