Additional Information
Sep-Pak PSA 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50/pk The Sep-Pak PSA 3 cc Vac Cartridge is designed for the removal of interfering substances, such as organic acids and salts, from biological fluids and water samples. The lab equipment is commonly used for sample preparation in environmental and clinical chemistry applications, such as the analysis of drugs, metabolites, and toxins in urine and plasma samples. The Sep-Pak PSA 3 cc Vac Cartridge contains a strong anion-exchange sorbent, which binds to the negatively charged interfering substances in the sample. The cartridge is pre-conditioned with a polar solvent, such as methanol or acetonitrile, to activate the sorbent. After loading the sample onto the cartridge, the interfering substances are retained on the sorbent while the desired analytes pass through. The analytes can then be eluted from the cartridge with an appropriate solvent, such as water or a weak acid. The Sep-Pak PSA 3 cc Vac Cartridge is specifically designed for the purification of polar and non-polar compounds from aqueous samples, such as biological fluids, food and beverage samples, and environmental samples. The lab equipment is particularly beneficial in the removal of interfering substances such as organic acids, fatty acids, and lipids and for the enrichment of target analytes such as amino acids, nucleosides, and organic bases. The Sep-Pak PSA 3 cc Vac Cartridges are produced in excellent manufacturing facilities that guarantee the industry's highest quality standards, including the cGMP (current Good Manufacturing Practices), ISO 9001, and ISO 13485. To make sure you get the best lab equipment and accurate findings, each Sep-Pak PSA 3 cc Vac Cartridge is put through a rigorous QC test.
