Description

General description

HPLC cartridge

LiChrospher^® NH2 posses polar and hydrophobic properties and can be used for normal phase, reversed phase and ion exchange chromatography. Typical applications are the separations of carbohydrates by reversed phase chromatography or the separsation of nucleotides by ion exhange chromatography. This sorbent is packed into a LiChroCART 250-4 HPLC cartridge. The connection to the HPLC system is being accomplished by use of the manu-CART NT cartrige holder (1.51486).

Application

• α-Naphtholbenzein based heterocyclic sensor for detection of Cu(II) ions.: This study introduces a novel application of 1-Naphtholbenzein as a fluorescent sensor for the detection of copper ions in various environmental samples. The heterocyclic design enhances the sensitivity and selectivity, making it valuable for real-time monitoring and ecological studies. This innovation not only advances the field of chemical sensors but also contributes to environmental chemistry by providing a tool for the detection of potentially toxic metal ions (Saini et al., 2024).
