Hitachi HPLC columns of the LaChrom and LaChromUltra series offer various surface chemistry for HPLC and UHPLC applications with complete solutions to meet the most challenging chromatographic demands. They feature four octadecylsilane (C18) chemistries, which form a part of the total eight unique surface chemistries offered by these columns on high-purity silica.
The C18 resins are the most widely employed, and can deliver high-quality, optimized separations and an even more enhanced range of physical and chemical properties that can be generated by "endcapping" these resins.
Column properties can be counterbalanced with the properties of mobile phase and the sample, which results in separations that are of high efficiency and resolution.
