ZORBAX HILIC Plus UHPLC guard column with inner diameter 2.1 mm, length 5 mm and particle size 1.8 µm. One package contains 3 columns. ZORBAX HILIC Plus is ideal for the retention of small polar analytes and is recommended for EPA method 1694. By using high purity ZORBAX Eclipse Plus Silica, they exhibit high LC/MS sensitivity and excellent peak shape, especially for polar, basic analytes. The robustness and reproducibility of HILIC separations on ZORBAX columns enables the switch from challenging, often MS-incompatible ion pair chromatography to normal phase applications. Rapid Resolution High Definition (RRHD) technology keeps columns stable up to 1200 bar. This ensures fast, high-resolution separations of even the most complex samples.Meer tonenMinder tonen
