LaChromUltra II C18

High durability and pressure resistance enable high resolution performance.
With LachromUltra C18 II columns, UHPLC will be applicable from ultra high speed analisys to ultra high resolution analysis.

The LaChromUltra II column is packed with composed material comprised of organic-inorganic silica, providing improved physical and chemical durability over that of conventional silica gel particles.
To maximize the high pressure performance inherent to UHPLC, a 250 mm long column with 1.9 µm particles is added to the product lineup.
UHPLC will be applicable from ultra high speed analisys to ultra high resolution analysis.

Features

The physical and chemical durability of organic-inorganic silica is improved over that of conventional silica, which achieved high pressure tolerance. Based on the performance, a 250 mm long column is added to the product lineup.
The high resolution columns with theoretical plate number 50,000 fully work in the application of related compounds analysis , multicomponent analysis and so on.
Furthermore, by connecting 2pcs of 250 mm columns, ultra high resolution will be achieved with theoretical plate number 100,000.
