solid phase extraction cartridge c18
Solid phase extraction cartridge C18 represents a crucial tool in analytical chemistry and sample preparation. This innovative device utilizes octadecyl carbon chain bonded silica (C18) as the stationary phase, offering exceptional capabilities for separating and purifying various compounds. The cartridge consists of a plastic or glass housing containing C18 modified silica particles, designed to effectively retain non-polar to moderately polar compounds from aqueous solutions. The mechanism works through hydrophobic interactions between the analytes and the C18 chains, allowing for selective retention and subsequent elution of target compounds. These cartridges excel in applications across pharmaceutical analysis, environmental monitoring, food safety testing, and biological sample preparation. The technology enables efficient cleanup of complex matrices, concentration of analytes, and removal of interfering substances. With its robust design and reliable performance, the C18 cartridge can handle diverse sample types, from water and beverages to biological fluids and environmental samples. The standardized format ensures compatibility with various laboratory equipment and automation systems, while the optimized pore size and particle distribution guarantee consistent separation results. Modern C18 cartridges feature enhanced chemical stability, reduced secondary interactions, and improved recovery rates, making them indispensable tools in modern analytical laboratories.
