Structured to assist in consistent experimental procedures, the Hplc Column Nucleodur® C 18 Gravity, 5 μm, 250 mm, 21 mm features a high density C 18 phase based on high purity NUCLEODUR® silica gel. Its endcapping suppresses unwanted polar interactions between the silica surface and the sample, making it ideal for the separation of basic and other ionizable analytes. With an enhanced pH stability, LC/MS suitability, and superior base deactivation, this column is a perfect choice for method development and valuable for RP applications. It comes packaged with an analytical HPLC column, instruction leaflet, and certificate of analysis.
