HPLC Method for Analysis of Magnesium Ion on Chromni Column

August 25, 2026

HPLC Method for Analysis of Magnesium on Chromni Column by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Magnesium.

Magnesium is an element with the symbol Mg. Magnesium ion has the chemical formula of Mg2+. It is a shiny grey metal with a high chemical reactivity, but low density and melting point. While magnesium is abundant in the earth’s crust, it is produced in the cosmos in large, aging stars. It is primarily used as a structural metal in a large variety of contexts from aircrafts to light sources and chemical reagents.

Magnesium can be retained and analyzed using the Chromni stationary phase column. The analysis utilizes an isocraticmethod with a simple mobile phase consisting of water and acetonitrile (MeCN) and TFA. Detection is performed using ELSD.

Condition

ColumnChromni, 4.6 x 150 mm, 3 µm, 100 A, surface coated
Mobile PhaseMeCN/H2O – 85/15%
BufferTFA – 0.1%
Flow Rate1.0 ml/min
DetectionELSD

HPLC ELSD Method for Separation of Metal Ions on Primesep 100 Column

October 4, 2005

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.
