MICRO HILIC COLUMNS FROM HILICON

Hilicon is a leading company in developing and manufacturing hydrophilic interaction liquid chromatography (HILIC) products for the separation of polar and hydrophilic compounds. It has recently started to expand its iHILIC-Fusion and iHILIC‑Fusion(+)product lines into a 1 mm microbore column format.

The initial products use a 3.5 μm particle for HPLC and will soon use 1.8 μm for UHPLC. The columnsutilize a PEEK-lined stainless‑steel column hardware that minimizes the undesirable surface interactions between samples and steel and achieve the best chromatography performance. They are versatilefor the LC–MS-based analysis of polar compounds in “omics” research, for example, metabolomics,proteomics, glycomics, and lipidomics, in the fields ofclinical diagnostics and pharmaceutical discovery.

The packed iHILIC stationary phases are charge-modulated amide silica particles that are covalently bonded with various neutral, positively charged, and negatively charged hydrophilic functional groups, following the company’s innovative and uniquesurface‑bonding technologies. iHILIC-Fusion is neutral and slightly negatively charged at pH 2–8, while iHILIC-Fusion(+) is constantly slightly positively charged. According to the company, the columns provide customized and complementary selectivity, ultimateseparation efficiency, ultra-low column bleeding, and are particularly suitable fo rLC–MS applications.

Furthermore, they also simplify method development and improve the productivity and data quality in chemical and biological analysis.
