General description
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 comparableto 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 25 mm length and 4.6 mm I.D. is the best choice for very rapid separations on any HPLC System and rapid method development.
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]

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
