Chromatography

We manufacture chromatography units ranging from Gas Chromatography, GC-MS, Ion Chromatography, Portable Ion Chromatograph, etc. In many laboratories, industries, and research organizations, chromatography is used to purify compounds, separate mixtures into their constituents, and test the purity of compounds.
