WebMixed-mode stationary phases were designed to retain and separate compounds with drastic difference in properties using one column and method. Carboxylic acids, amino acids and sugars are poorly retained in reversed-phase chromatography. Derivatization procedures, ion-pairing reagents and HILIC columns can be used tp analyze these … WebIon Pair Reagent for HPLC Appearance: Clear, colorless liquid Purity: NA Boiling Point: Slightly above 100°C Molecular Formula: C 16 H 38 NO 4 P Molecular Weight: 339.46 g/mol Specific Gravity (H 2 O = 1.0): 1.0 Suggested Storage Conditions: Tightly closed in a cool, dry, and well ventilated place. the roxy boston nightclub
Sodium 1-heptanesulfonate solid 22767-50-6 - Sigma-Aldrich
WebOne of the biggest problems with ion pairing is a result of the equilibrium between the ion-pairing reagent and the stationary phase. The equilibration process is very slow, and it is strongly influenced by the organic content of the mobile phase and the column temperature. Normally we think of the column equilibrating with the mobile phase in ... WebEffective retention of hydrophilic ionic and ionizable analytes without ion-pairing reagents; ...
