HPLC chromatography column Chromolith® RP-18

Appearance: conforms Carbon content: 17,0 - 18,6 % Pressure: ≤ 30 bar stability testing: conforms Performance (anthracene) Theoretical Plates (N/m) (Anthracene): ≥ 80000 Capacity factor (Anthracene): 3,9 - 4,6 Tailing (USP): 0,90 - 1,60 % Selectivity separation factor (anthracene/progesterone): 1,95 - 2,35 Application Salt pollution reduces turbidity, dissolved organic matter, and cyanobacteria in experimental vernal pool communities: Discusses environmental applications of calcium chloride, focusing on its use in managing ecosystems affected by salt pollution, demonstrating its role in environmental remediation and management. General description Chromolith® columns are made of monolithic silica with a characteristic bimodal pore structure. Chromolith® Performance RP-18 endcapped HPLC columns have macropores with 2 μm diameter, giving a column efficiency exceeding 80,000 plates/meter. The mesopores are 13 nm (130 Å) and the surface modification is octadecylsilane with full end-capping. Chromolith® Performance RP-18 endcapped columns fall under the USP L1 Classification. The column efficiency is comparable to a 5 μm particle size fully porous particulate column. Chromolith®Performance RP-18 endcapped columns are perfectly suitable for LC-MS applications. The column dimension of 100 mm length and 4.6 mm I.D. is the best choice for separations of complex samples on any HPLC System. The revolutionary, monolithic silica with its unique combination of macropores and mesopores enables: Rapid separations at very low column back-pressure High matrix tolerance, allowing time and cost savings with simplified workflows
