產(chǎn)品特點:

NUCLEOGEL® SUGAR · NUCLEOGEL® ION 300 OA

 

Polymer-based HPLC phases for separation of sugars

 

Features

 

 

Sulfonated spherical PS/DVB resins in different ionic forms; mean particle size 10 µm, pore size 100 Å
Separation mechanism includes steric exclusion, ligand exchange and partition effects, ligand exchange being the predominant force, since the hydrated metal ions form strong interactions with the hydroxyl groups of the sample molecules. The intensity of these interactions decreases in the sequence Pb, Ca, Na
Eluent in column for Ca, Na and Pb phases: water + 0.02 % azide
Recommended operating temperature: 6095 °C; maximum pressure 70 bar

 

 

NUCLEOGEL® ION 300 OA:
H+ form for separation of sugars, alcohols and organic acids ? USP L17
eluent in column 5 mM H2SO4

 

NUCLEOGEL® SUGAR Ca:
for separation of mono- and oligosaccharides, sugar alcohols ? USP L19

 

NUCLEOGEL® SUGAR Pb:
for separation of mono- and disaccharides from food and biological samples ? USP L34
 

 

NUCLEOGEL® SUGAR Na:
for separation of oligosaccharides from starch hydrolysates and food ? USP L58
