Exceed the standards for an HPLC Column
Symmetry® LC Columns are manufactured using high purity silica and tightly controlled manufacturing processes to ensure that you receive a column that exceeds the standards for HPLC column performance. No other silica-based LC column brand can match the column-to-column and batch-to-batch reproducibility of the Symmetry family. Symmetry Columns are available in column, cartridge, and guard formats to include:
1、Symmetry C18 and C8 chromatography columns that deliver maximum reproducibility
2、SymmetryShield RP18 and RP8 chromatography columns to provide superior peak shape
3、Symmetry300 C18 and C4 chromatography columns, which offer high recoveries of peptides and proteins
Symmetry Column Characteristics
Symmetry HPLC Columns for Reproducibility
You can rely on a Symmetry HPLC column for rugged and reproducible performance. Narrow column specification ranges minimize variation giving you the confidence that the methods you use today will continue to be used in the future.
Symmetry Shield Columns for Superior Peak Shape
SymmetryShield™ Columns feature Waters' patented embedded polar group technology that shields the silica's residual silanols from highly basic analytes at improves overall peak shape. Additionally, by placing the embedded polar group close to the silica surface, the activity of the surface silanols is further reduced. This imparts selectivity and retention that is different compared to the Symmetry C18 ligand.
Embedded polar group technology improves chromatographic peak shape and selectivity.
Symmetry300 Columns Deliver High Peptide Recovery
All Symmetry300™ columns are QC tested with peptide samples to ensure exceptional batch-to-batch reproducibility. These wide-pore(300Å), reversed-phase chromatography columns deliver superior performance when simultaneously separating hydrophilic and hydrophobic peptides, as well as neutral and highly basic peptides. Expect better performance using either high or low mass loads with a Symmetry300 column.
Symmetry300 C4 Columns provide superior peptide separation
VanGuard Column Protection
The often complex sample matrices encountered in pharmaceutical, natural product, environmental, and industrial chemical analysis prematurely shorten analytical column lifetime and degrade chromatographic performance. Waters VanGuard Cartridge Columns help improve analytical column performance by removing particulate and chemical contamination that may be present in the mobile-phase stream—without compromising chromatographic performance.
