Waters Corporation have introduced ACQUITY™ PREMIER Columns, a new family of premium sub-2-micron columns featuring MaxPeak™ High Performance Surface (HPS) technology. The columns are for use with any brand of UHPLC system and can measurably improve data quality by mitigating the loss of sample analytes due to analyte-to-surface interactions. Designed for the analytical laboratory seeking to exercise greater control over their chromatographic separations, the columns improve sample throughput, assay-to-assay reproducibility and overall confidence in analytical results.
“Analyte loss due to non-specific adsorption is a significant problem that deserves more attention because of the cost of wasted effort and lost productivity. Most of the time, scientists don’t even know what they are missing. There are workarounds but they come with their own problems,” said Erin Chambers, Vice President, Chemistry, Waters Corporation. “So we challenged our engineers to come up with an innovative solution that removes one of the biggest impediments to getting quality results. Our ACQUITY PREMIER Columns rectify a problem that has long-plagued chromatography analyses and enable scientists to create the best quantitative and qualitative analytical methods whether for discovery, development or quality control applications.”
Waters™ ACQUITY PREMIER Columns feature MaxPeak HPS technology, a hybrid organic/inorganic surface technology that forms a barrier surface layer between the sample and the stainless steel column. The benefits of this new technology are many, among them:
Willy Verluyten and Irene Suarez with Janssen Pharmaceutica NV, Belgium, evaluated the columns for their own methods development work.
“The Waters ACQUITY PREMIER Peptide BEH C18 300Å Column shows an excellent degree of specificity and selectivity in denaturing and non-denaturing analysis of synthetic oligonucleotides, due to the absence of non-specific binding properties of this new column hardware in combination with great stationary phase performance,” says Verluyten. “The Waters ACQUITY PREMIER Column is a highly valuable addition to our column test package for the future development of synthetic oligonucleotides analytical methods.”
The introduction of ACQUITY PREMIER Columns sheds light on a well-known problem among scientists: the adsorption of sample analytes to the interior wall of steel analytical columns. This is a significant problem when analyzing metal-loving analytes ranging from organic acids and organophosphates to oligonucleotides, peptides, glycans and phospholipids. Organizations are known to spend days and tens of thousands of dollars of precious product (e.g. oligonucleotides), just to condition an LC column prior to analysis in order to minimize adsorptive analyte losses.
Kerri Smith, Principal Scientist, at Waters Corporation has studied organic acid metabolites that play a role in diabetes, cancer and heritable diseases. “If you lose a low-level analyte because of analyte-to-metal adsorption, and don’t detect it in its correct concentration, you’ll never understand if it’s playing an important role in the disease you are studying,” said Smith.
Waters ACQUITY PREMIER Columns are ideal for both small molecule and biopharmaceutical applications and are manufactured with trusted sub-2-micron particle technologies; Bridged/Ethyl Hybrid (BEH) for maximum column stability, Charged Surface Hybrid (CSH) the best choice for mass spectrometry analysis, and High Strength Silica (HSS) for increased retention when analyzing challenging polar compounds. The columns are now available worldwide from Waters.
