Additional Information
Symmetry C18 Column, 100Å, 3.5 µm, 2.1 mm X 50 mm, 1/pk On a high purity, base-deactivated silica, symmetry C18 columns have monofunctionally bound C18 ligands. The industry's tightest column requirements are found in symmetry columns, which leads to highly reproducible chromatographic results. You can achieve high repeatability in chromatographic findings by adding the Symmetry C18 Column to your system. This is made possible by the high purity base-deactivated silica combined with the monofunctional bound C18 ligand employed in the production of the Symmetry C18 Column. One of the narrowest ligand surface coverage (ligand density) specifications in the market is found in the Symmetry C18 Column, which produces minimal variations in resolution and repeatable batch-to-batch results. You achieve great repeatability year after year in your lab with the Symmetry C18 Column. Since the Symmetry C18 Column doesn't need to be revalidated and you won't have to build new procedures for each batch of new columns, you will avoid the labor and lab expenditures that traditionally analytical columns incur due to the ongoing monitoring and QC testing they require. The Symmetry C18 Column was among the most reproducible HPLC columns thanks to the high purity raw materials and column packing techniques used in its construction by Waters. The Symmetry C18 Column is produced in specially designated Waters facilities that are cGMP, ISO9001, and ISO13485 certified, where the strictest conditions are guaranteed, and each step of the manufacturing process is meticulously controlled. This makes it possible to produce Symmetry C18 Columns with the strictest market criteria, ensuring reliable results each and every time. You can browse through our catalog or review our website to shop for lab equipment to meet all your laboratory requirements. We recommend you also check out the Symmetry C18 VanGuard Cartridge, 100Å, 3.5 µm, 2.1 mm X 5 mm, 3/pk; Symmetry C18 VanGuard Cartridges are used to extend analytical column lifetime and performance by removing particulate contamination from the mobile phase stream. This cartridge is optimized to protect all 2.1 mm and 3.0 mm I.D. Symmetry C18 analytical columns containing 3.5 µm sorbent particles.

FAQ
What Steps Are Taken To Equilibrate A C18 Symmetry Column? To equilibrate the column, use at least 10 column volumes of the mobile phase you wish to utilize. To avoid mobile phase buffers precipitating out on your column or in the system, flush the column with five column volumes of a water/organic solvent mixture using the same or less solvent concentration as in the intended buffered mobile phase.
