Available with optimised 2 μm particulate silica, these UHPLC columns, based on Purospher® STAR RP-18 endcapped, are ideal for ultra-fast applications, where resolution, sensitivity and sample throughput are crucial. They are the first choice for high throughput screening and QC analyses, process monitoring, method development and LC-MS applications. Due to its balanced selectivity, Purospher® STAR RP-18 endcapped UHPLC columns cover almost all demanding separations with tailing-free chromatograms. Purospher® STAR RP-18 endcapped 3 μm columns are recommended for difficult samples where clogging and back pressure present an issue.

• In UHPLC environment, speed is increased by a factor of 10
• Solvent consumption is drastically cut
• Excellent peak shape for all types of acidic, basic and metal-chelating analytes
• Extraordinary pH stability from pH 1,5 to 10,5 for an extremely wide application range
• Enhanced sensitivity due to improved signal-to-noise ratio

Hibar® HR columns are complete with end fittings and pressure stable (600 bar) for UHPLC use.
