This is a new HPLC column for silver ion chromatography based on zirconium phosphate! It can be applied to samples in the food sector and organic synthesis field!

"Silver column KANTO" is a new HPLC column for silver ion chromatography based on zirconium phosphate. It is particularly useful for the separation, analysis, and purification of fats and oils with complex compositions. This product overcomes the challenges of conventional silver nitrate-impregnated silica gel, offering high safety and distinctive separation capabilities, with potential applications beyond the food sector. 【Features】 ■ Separation of cis/trans isomers Generally, the cis isomer has a higher stability of the complex formed with Ag+ than the trans isomer, resulting in the cis isomer being retained more strongly while the trans isomer elutes first. ■ Separation of positional isomers Regardless of the number of carbon atoms, the further the double bond is from the carbonyl carbon, the faster it elutes. Additionally, in the separation of aromatic compounds, they elute in the order of o-isomer, m-isomer, and p-isomer. ■ Separation of fatty acids with different carbon chain lengths Fatty acids with a higher number of carbon atoms elute faster. Moreover, those with more double bonds are retained more strongly. ■ Separation of compounds with multiple double bonds Non-conjugated double bonds are retained more strongly than conjugated double bonds. Furthermore, the closer the double bonds are to each other, the faster they elute. For more details, please download the catalog or feel free to contact us.

basic information

"Silver column KANTO" is a new HPLC column for silver ion chromatography based on zirconium phosphate. Thanks to the principles of silver ion chromatography, it enables the separation of unsaturated fatty acids and geometric isomers. Additionally, it has less silver ion elution compared to previous silver ion chromatography supports, promising higher durability and reproducibility. 【Features】 ■ A packing material with silver supported on zirconium phosphate By supporting silver on zirconium phosphate, it offers superior durability and higher reproducibility compared to previous silver ion chromatography supports. ■ Utilizes the property of organic compounds' unsaturated bonds to form complexes with silver ions. ■ Developed at the Kanto Chemical Research Institute. ■ Capable of separating geometric isomers. ■ Separation is possible based on the number of double bonds and their locations. ■ Applicable materials: - Food sector: fat content (oils, fatty acids) - Organic synthesis sector: cis-trans isomers For more details, please download the catalog or feel free to contact us.
