Ion Chromatography remains the indispensable tool for the analysis of polar molecules and inorganic ions in complex matrices. In 2026, the focus is on Microbore IC and High-Pressure systems, which allow for faster separations with significantly less solvent waste, aligning with global "Green Chemistry" initiatives. The ability to detect trace levels of per- and polyfluoroalkyl substances (PFAS) in drinking water has made IC a frontline technology in environmental protection and public health monitoring.
In the pharmaceutical sector, IC is increasingly coupled with Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for speciation analysis. This is critical for determining the oxidation state of elements; for example, distinguishing between the relatively harmless Cr(III) and the highly toxic Cr(VI) in drug formulations. As biological drugs become more complex, the role of IC in characterizing "charge variants"—small changes in the ionic charge of a protein that can affect its efficacy—has become a mandatory component of the…
