A premium inert coating applied to the stainless-steel surface of our LC columns reduces nonspecific binding of chelating analytes, enabling sensitive analysis and smooth integration of peaks. Combined with Restek’s selective stationary phases, these new inert LC columns are ideal for the analysis of metal-sensitive compounds.\u003c\/p\u003e\u003cp class=\"richp\"\u003eRestek chemists became the first to combine the speed of superficially porous particles (also known as SPP or \"core-shell\" particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times with existing HPLC and UHPLC instrumentation.\u003c\/p\u003e\u003cp class=\"richp\"\u003eAnalyzing polar compounds using liquid chromatography has historically been a challenge due to poor retention, long equilibration times, low sensitivity, and the need to mitigate these problems with time-consuming sample derivatization or complex ion-pairing approaches. However, with the development of the Raptor Polar X column—a novel column that is specifically designed for the analysis of a broad range of polar compounds—scientists can avoid these problems. These new columns feature a unique phase chemistry that combines both HILIC and ion-exchange retention mechanisms on a single ligand.Because this ligand is bound to superficially porous particles, Raptor Polar X columns both reliably retain and efficiently separate a wide variety of polar analytes with simple mobile phase changes. By analyzing polar compounds on a column that provides purpose-built resolving power, you can avoid complex sample preparation procedures, save time and money, and reduce opportunities for error. Simplify the analysis of polar compounds with the resolving power of Raptor Polar X columns from Restek.\u003c\/p\u003e\u003cp class=\"richp\"\u003e\u003cb\u003eFeatures \u0026amp; Benefits:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eInert LC column technology reduces nonspecific binding of chelating analytes, enabling sensitive analysis and smooth integration of peaks.\u003c\/li\u003e\n\u003cli\u003eIdeal for the analysis of metal-sensitive compounds.\u003c\/li\u003e\n\u003cli\u003eReliably analyze a wide variety of polar analytes (acidic, basic, and neutral) without time-consuming derivatization or complex ion pairing.\u003c\/li\u003e\n\u003cli\u003eSwitch between HILIC and ion-exchange retention modes with simple mobile phase changes and short equilibration times.\u003c\/li\u003e\n\u003cli\u003eRaptor 2.7 μm core-shell particles provide UHPLC-like speed and efficiency on all makes and models of LC systems.\u003c\/li\u003e\n\u003cli\u003eIdeal for increasing sensitivity and selectivity in LC-MS analyses.\u003c\/li\u003e\n\u003cli\u003eIncluded in the Quick Polar Pesticides (QuPPe) method published by the European Union Research Laboratory for Single Residue Methods.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp class=\"richp\"\u003e\u003cb\u003eStorage Conditions:\u003c\/b\u003e When not in use, Raptor Polar X columns must be kept in 100% acetonitrile.
