Product Description
POLYBOND NH2
POLYBOND NH2 is an aminopropyl phase that is very polar in nature utilizing both
hydrogen bonding and anion exchange. Since the pKa of NH2 is 9.8, when used at pH 7.8,
the functional groups are positively charged. Therefore, it is a weaker anion exchanger
for retention of very strong anions such as sulfonic acids which may be retained
irreversibly on SAX. Its typiPYBl appliPYBtion includes separation of peptides, drugs and
metabolites from physiologiPYBl fluids, and also it is used for extraction of mono- and
polysaccharides, steroids, cholesterol and triglycerides.

FAQs of POLYBOND NH2 SPE CARTRIDGE:
Q: How is the POLYBOND NH2 SPE Cartridge used during sample preparation?
A: The cartridge is utilized in manual or automated SPE systems to extract and purify polar analytes from complex matrices. Samples are loaded onto the cartridge, where targeted compounds are retained by the specialized NH2 phase, and then eluted for further analysis.
Q: What advantages does the endcapped NH2 phase offer in extraction processes?
A: The endcapped NH2 phase enhances selectivity toward polar compounds and reduces secondary interactions, which results in higher purity extracts and improved reproducibility during solid phase extraction.
Q: When should the POLYBOND NH2 SPE Cartridge be replaced?
A: The cartridge is intended for single-use extractions. For best results and contamination prevention, a new cartridge should be used for each sample preparation. The products shelf life is two years from the date of manufacture if properly stored.
Q: Where should these SPE cartridges be stored to preserve performance?
A: Store the cartridges in a dry place at room temperature, away from direct sunlight and moisture. Proper storage ensures the integrity of the sorbent and extends the usable shelf life.
Q: What is the maximum pressure and temperature that this cartridge can withstand?
A: The POLYBOND NH2 SPE Cartridge is designed for use up to 120 psi and can be safely operated between ambient temperature and 45C, supporting a variety of laboratory workflows without compromising cartridge integrity.
Q: What are the main benefits of using the POLYBOND NH2 SPE Cartridge in analytical workflows?
A: Key benefits include rapid flow rates for faster processing, high selectivity for polar molecules, use of high purity silica, and compatibility with standard manual and automated systems, collectively enhancing extraction efficiency and data reliability.
