Applications:


Separation of Metal Ions on Primesep 100 Column



Primesep 100 separates the monovalent cations, lithium, potassium, and sodium, and the divalent cations, zinc, manganese, and calcium. The cations are resolved by cation exchange. The mobile phase mixture of water, acetonitrile (MeCN, ACN) and trifluoroacetic acid (TFA) is evaporative light scattering detection (ELSD) compatible.



Application Analytes:

Calcium
Chloride
Lithium
Magnesium
Potassium
Sodium
Zinc

Simultaneous Analysis of Glucose, Sodium, Potassium and Calcium Ions

HPLC Analysis of Calcium Ions in Maple Syrup

 

Application Notes: maple syrup primarily consists of sucrose and other sugars, but also has small amounts of amino acids (arginine, threonine, proline), organic acids (malic and fumaric), vitamins (niacin and riboflavin) and traces of minerals (Na, K, Ca, Mn, Mg, Zn ions). One analysis performed on maple syrup is calcium ion determination. A Primesep 100 column was used in cation-exchange mode to isolate calcium ion from other components of the maple syrup. This method can be used for quantification of calcium ion by ELSD/CAD. Limit of detection depends on the type of ELSD/CAD detector used but usually reaches 20 ppm

Application Columns: Primesep 100
Application compounds: calcium ions, Maple Syrup
Detection technique: LC/MS, ELSD/CAD
