Ion chromatography is a high-resolution analysis technique, in order to determine the ionic contamination on the component assembly according to type and quantity.
Unlike simpler methods of measurement, such as the use of contaminometers or omegameters whereby the total ionic content is calculated as an equivalent to sodium chloride, ion chromatography provides both a quantitative and qualitative resolution of the ions.
This method makes it possible to detect weak organic acids on printed circuit boards or soldered assemblies that can cause temporary leakage currents enabling an initial risk assessment to be made.
Ion chromatography enables the identification of critical hygroscopic ions, such as those of chloride or bromide. These ions can extract moisture from the
ambient air onto the coated assembly. The consequential damage appears in the form of field malfunctions including known error patterns like electrochemical migration.
