Waters, WAT020535, Sep-Pak Aminopropyl (NH2) Plus Short Cartridge, 360 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk

Sep-Pak Amino Propyl (NH2) Plus Short cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These versatile cartridges can attach easily to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.

Additional Information
Sep-Pak Aminopropyl (NH2) Plus Short Cartridge, 360 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk Amino Propyl (NH2) Plus Sep-Pak Short cartridges have a silica-based bound phase that is moderately polar and has a weakly basic surface. The sorbent can be employed as a weak anion exchange in aqueous media below pH 8 or as a polar sorbent with varying selectivity for acidic/basic analytes. Applications include phenol and phenolic pigment extraction, petroleum fractionation, saccharide extraction, and drug and metabolite extraction. These adaptable cartridges are simple to attach to pumps and syringes for dependable, positive-pressure flow to shorten the processing time for samples. They can also be utilized on vacuum-assisted flow devices and some automated systems, and they can be fitted with replaceable reservoirs. The Sep-Pak Aminopropyl (NH2) Plus Short Cartridges have been meticulously designed to guarantee that you receive the product properly sealed inside a non-contaminating poly-foil pouch; this guarantees that there are no contaminants get inside, and it maintains product integrity and packing inactivity. In order to produce Sep-Pak Aminopropyl (NH2) Plus Short Cartridge, Waters creates and manufactures the packaging, making sure it meets the highest industry requirements. In order to guarantee consistent results every time, the packing is clean, dry, and gives the best particle size distribution, pore size, and surface area.

On our website, you can also contact a member of our foreign support staff. Our customer support agents can assist you if you have any questions or problems. They can also assist you in making the right decisions for your chromatographic and laboratory requirements. We recommend reviewing the MassPREP Protein Standard Mix as well; The MassPREP Protein Standard Mix includes ribonuclease A, cytochrome c, bovine serum albumin, myoglobin, enolase, and phosphorylase b. This combination contains several proteins with various molecular weights, isoelectric points, and hydrophobicities. These characteristics provide the user with a desirable intact protein mixture that can be applied in many ways. It is suggested that this standard be used frequently for assessing column and system performance, similar to the QCRM product line.

FAQ
What Is The Significance Of Quaternary Amines In Liquid Chromatography? A quaternary amine, which is an amine salt, possesses a positively charged nitrogen atom with four attached groups. These positively charged surface-active compounds, also referred to as cationic surfactants, readily bind to the negatively charged surfaces of most microorganisms. Widely used as disinfectants and cleaning agents, they find applications across various industries.
