BioSuite C18 PA-A Column, 100Å, 3 µm, 2.1 mm X 50 mm, 1K - 15K, 1/pk

The BioSuite C18 PA-A Column is a low-ligand density, dielectrically bonded silica-based column. It has been meticulously engineered for good polar peptide retention, making it an excellent candidate for use as a column in LC-MS applications using formic acid (FA), which decreases ion suppression. Traditional HPLC separations employing TFA concentrations, such as 0.025 percent TFA, function well with the BioSuite C18 PA-A Column.

The BioSuiteTM Peptide Analysis columns are made up of two superior reversed-phase column chemistries that are specially designed for peptide mapping from simple to complex digests. BioSuite PA Columns come in a variety of sizes and combinations for LC and LC/MS applications, including 250 mm lengths for ultra-high resolution. These BioSuiteTM PA-A and PA-B columns are QC tested specifically for peptide mapping and provide high batch-to-batch consistency for reliable results. BioSuiteTM C18 3m PA-A is a difunctional bonded, low ligand density, silica-based, reverse-phase column with a 100 ligand density, while BioSuiteTM C18 3.5m PA-B is a 300 ligand density, monofunctional, silica-based reverse-phase column with a high ligand density.

The BioSuite C18 PA-A Column column is made under the tightest cGMP, ISO 9002 conditions in a dedicated Waters chromatography chemistry production plant. Silica-based and polymeric chromatography materials are manufactured and packed into columns and solid-phase extraction devices at the manufacturing site. This assures that you receive top-of-the-line laboratory equipment that produces consistent and trustworthy analysis findings.

The septum will enable you to replace the pre-slit PTFE/Silicone septum of the glass vials and offers sufficient venting to prevent vacuum formation in the sample vial. It delivers outstanding sample-draw reproducibility while exhibiting excellent resealing characteristics.
