In recent years, instrumental techniques have gained prominence for their speed and precision. Ion chromatography, for instance, separates and quantifies ions based on their affinity to a resin within a chromatographic column. The sulfate ions are eluted and detected, typically by conductivity or UV detection after reaction with a reagent that enhances their detectability. The area under the peak in the chromatograph is proportional to the concentration of sulfate, which can then be translated to TiO2 content through appropriate calculations.

In 1970, Japanese scholars studied the phase diagram of iron oxide microcrystalline formation, which laid a theoretical foundation for the preparation method of iron oxide yellow crystal seed. According to the research results, iron yellow crystal seeds can be formed under acidic or alkaline conditions. Because iron yellow is a crystal structure, in order to crystallize into pigment particles, it must first form crystal nucleus and become crystal seed, and then the crystal nucleus grows into iron yellow. Otherwise, only thin and dim color paste can be obtained, which does not have pigment properties. Acid process can be divided into iron sheet process and drop addition process.
