Waters Corp ACQUITY Premier Offers Metal-Free UHPLC Flow Path
Waters Corp's ACQUITY Premier System eliminates metal contact in sample flow paths, boosting recovery for phosphorylated peptides and metal-sensitive compounds.
Waters Corporation has unveiled the ACQUITY Premier System, a significant upgrade to its established ultra-high-performance liquid chromatography platform that removes metal from the sample flow path entirely, targeting a persistent pain point in bioanalytical research and quality control workflows.
The core engineering change directly addresses two well-documented frustrations in biopharma labs: erratic peak shapes and unexplained compound losses during assays. Metal surfaces inside conventional UHPLC systems can interact with certain analytes, compromising data integrity before results ever reach a scientist's screen.

Phosphorylated peptides and metal-binding compounds are particularly vulnerable to those interactions, making reproducible separations difficult in regulated environments where data robustness is not optional. The Premier's metal-free flow path is designed to eliminate that variable, improving analyte recovery and giving method development teams cleaner, more consistent results.
Waters is positioning the system squarely at biopharma quality control and method development groups operating under demanding research and regulatory conditions. By resolving ion adsorption artifacts at the hardware level rather than relying on mobile-phase additives or workaround protocols, the Premier aims to reduce assay troubleshooting time and accelerate method validation timelines.
