LaChromUltra II Series

VWR® Hitachi LachromUltra II C18-AQ HPLC/UHPLC Column, 120Ã, 2µm, 3mm ID x 75mm Length, 1/Pk

Part Number: 891-5025

• Has the same properties as LaChrom II (3 µm,5 µm) but in different sizes.
• It is easy to interchange analysis methods between UHPLC and HPLC.
• High durability and pressure resistance enable performance. 
• Low-Carbon C18 column
• Compatible with aqueous mobile phases including 100% water
• Useful for separating highly polar compounds including saccharides, nucleic acids and organic acids.

Specifications:

It has been generally accepted that high resolution analyses of impurities and structural analogs of synthetic compounds, such as medicines and chiral molecules, are challenging, even with UHPLC. Now, however, the newly developed high resolution column, LaChromUltra II, designed for UHPLC applications with system pressures up to 140 MPa can achieve more advanced separation analyses and industry-leading performance.

An inorganic-organic composite type silica material, the physical and chemical durability of which is improved relative to the conventional silica gel particle, is adopted for the LaChromUltra II column. In order to fully utilize the high system pressure of UHPLC, 250 mm long columns with 1.9 μm particles can be lined up in series. The useful application of UHPLC can be expanded to high resolution analyses, and is not limited to ultra high-speed analyses.

This C18 column, with a characteristic of the excellent peak symmetry, has a wide application range because of the superior alkali resistivity as well as the low adsorption. Mobile phases with a wide pH range between 1 and 12 can be used and therefore, it is possible to freely control the retention and selectivity for ionic compounds

The LaChromUltra II columns are 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 has been added to the product lineup.

Features

• The physical and chemical durability of organic-inorganic silica is improved over that of conventional silica, acieving high-pressure tolerance.
• Based on the performance, a 250-mm-long column has been added to the product lineup.
• The high-resolution columns with theoretical plate number 50,000 fully work in the application of relate- compound analysis, multicomponent analysis, and more. Furthermore, by connecting 2 pieces of 250-mm columns, ultrahigh resolution can be achieved with theoretical plate number 100,000.
