Descripción general

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:

Aplicación


  • 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).
