GRACE Zirchrom色谱柱

ZirChrom® Columns • Better pH and thermal stability than silica-based columns • More efficient than polymer-based columns • Widest range of reversed-phase selectivities ZirChrom Separations, Inc. produces HPLC columns based on 3μm zirconia (zirconium oxide) particles. These columns are more rugged and durable than silica-based columns and more efficient than polymer-based columns. ZirChrom® normal-phase and reversed-phase columns can be used across the entire pH range (1–14) and are thermally stable to 200°C. Additionally, zirconia’s silanol-free surface produces sharp, symmetrical peaks for amines without mobile phase modifiers. 了解更多或订购产品，请致电耐士科技全国服务热线：400-188-0725
