Which analytical method is used for inorganic acids?

Ion chromatography is the analytical method specifically designed for analyzing inorganic acids due to its ability to separate and quantify ionic species in a solution. The technique utilizes a stationary phase to interact with ions in the sample, allowing for their separation based on their charge and size. Inorganic acids, which dissociate in water to produce ions, are well-suited for ion chromatography, making it an effective choice for their analysis.

This method does not rely on the volatility of compounds, which is essential for gas chromatography, nor does it require the complex fragmentation processes of mass spectrometry. High pressure liquid chromatography (HPLC), while versatile for various analyses, is typically more suited for larger, non-ionic compounds than for the direct analysis of inorganic acids. Thus, ion chromatography stands out as the most appropriate and effective method for determining the concentration and presence of inorganic acids in a sample.
