一般說明
Ion-pairing reagents, when used as mobile phase additives, promote the analysis of ionic and highly polar substances on reversed phase HPLC columns. The purity of mobile phase additives is of highest significance for their effective application. Sigma-Aldrich makes available a variety of tailor-made reagents for anionic (quaternary ammonium and phosphonium salts) and cationic (alkanesulfonates) separations. All mobile phase additives are tested thoroughly with special consideration on the demands of modern reversed phase HPLC:
應用
- pH Standardization in Analytical Chemistry: Buffers serve as critical components in the batch-to-batch reproducibility studies for primary pH methods, ensuring high precision in pH measurement across various scientific disciplines, from pharmaceuticals to environmental science (Asakai et al., 2024).

A new water-soluble conjugated polymer containing fluorene and boron-dipyrromethene repeat units in the backbones (PBF) that exhibits red emission was synthesized and characterized. Cationic PBF forms uniform nanoparticles with negatively charged disodium salt 3,3'-dithiodipropionic acid (SDPA) in aqueous solution through

The prospect of enhancing the condensation rate by decreasing the maximum drop departure diameter significantly below the capillary length through spontaneous drop motion has generated significant interest in condensation on superhydrophobic surfaces (SHS). The mobile coalescence leading to spontaneous drop

Potassium homeostasis is crucial for living cells. In the yeast Saccharomyces cerevisiae, the uptake of potassium is driven by the electrochemical gradient generated by the Pma1 H(+)-ATPase, and this process represents a major consumer of the gradient. We considered that
