Allgemeine Beschreibung

Chromolith® columns are made of monolithic silica with a characteristic bimodal pore structure.

Chromolith® HighResolution RP-18 endcapped columns have macropores with 1.15 μm diameter, giving a column efficiency exceeding 140,000 plates/meter. The mesopores are 15 nm (150 Å), the surface modification is octadecylsilane with full end-capping.

Chromolith® HighResolution RP-18 endcapped columns fall under the USP L1 Classification. The column efficiency is comparable to a 2.7 to 3 μm particle size fully porous particulate column. Chromolith® HighResolution RP-18 endcapped columns are perfectly suitable for LC-MS applications.
The column dimension of 150 mm length and 4.6 mm I.D. is the best choice for high-resolution separations of complex compound mixtures 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
—Cost-savings due to extended column lifetimes
—Connection of columns, flow gradients and the use of mobile phases with higher viscosity

The recommended Guard-columns are:
Chromolith® HighResolution RP-18 endcapped 5-4.6 guard cartridges (3 pieces) [1.52025]
with the Chromolith® Guard Cartridge Holder 5 mm x 4.6 mm [1.52032]
The Chromolith® column coupler can be used to significantly increase the separation efficiency of Chromolith® columns by coupling several columns in series (up to 100,000 plates/per column). [1.51467]

Validated HPLC method (based on Ph. Eur. Monograph 2668) for quantifying catechins and caffeine in decaffeinated green tea using a Chromolith® High Resolution RP-18e column with advantages in terms of backpressure and matrix robustness.

Monolithic silica HPLC columns enable high-throughput analysis at low back pressure without loss of separation efficiency or peak capacity.

Niedermolekulare Verbindungen, sogannte Small Molecules, sind neutrale und ionische Verbindungen mit einem Molekulargewicht, das üblicherweise unterhalb von 900 Dalton liegt. Diese Verbindungen können durch HPLC, UHPLC und LC-MS vornehmlich unter Verwendung von Kieselgelpartikeln oder monolithischen stationären Phasen mit einem breiten Spektrum von „Säulenchemien“ (Modifikationen) effektiv getrennt und analysiert werden.

Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).
