Analysis Examples
Examples of Cation Analysis

Shim-pack IC-C4 is a cation analysis column for non-suppressor IC. Because the pH of the mobile phase can be changed by selecting a
different combination of acid and base in eluent, non-suppressor IC enables various kinds of analysis.

High Resolution of Na+ and NH4+
High resolution of Na+ and NH4+ has been achieved by improving the peak shape of Na+. The influence on the peak shape of NH4+
from a high concentration of Na+ has been reduced, making it possible to analyze tap water of normal concentration under standard
mobile phase conditions. The resolution can be further improved by using a mobile phase treated with 18-crown-6 additive.

Analyses of a Standard Mixture of 5 Cations

Flexible Mobile Phase Selection
Due to the features of non-suppressor IC, flexible mobile phase composition can be used. Besides normal inorganic cations,
Shim-pack IC-C4 is capable of analyzing transition metals by using a mixed mobile phase.

(P/N: 228-41616-91)
Mobile Phase : A) 2.5 mmol/L oxalic acid
B) 2.5 mmol/L methanesulfonic acid
A/B = 60/40 (v/v)
Flow Rate : 1.0 mL/min
Col. Temp. : 40 °C
