Waters has now worked on a new design improvements in the Alliance HPLC (high performance liquid chromatography). The updated system will maintain the performance specifications and control algorithms of the Alliance to ensure that analysts can seamlessly replicate their existing methods.

“The Alliance has been the benchmark for HPLC in the laboratory for nearly two decades. Because of its dependability, high quality and flexible operation, these systems are used frequently to run methods varying from USP monographs to polymer analyses,” said Ian King, vice president of Separation Science for the Waters Division.

“Since its introduction, the Alliance HPLC System has been continually enhanced accommodating an enormous range of separation challenges. Waters will continue its commitment to upgrading the Alliance HPLC System with the assurance that any changes will not affect established, validated HPLC methods,” he added.

Beyond updated electronics and user interface, the Alliance system is ideally suited to help scientists enhance their HPLC methodologies through use of Waters eXtended Performance [XP], columns. These columns belong to Waters’ platform of scalable particle size chemistries, which includes the patented surface charged column chemistries, which due to their wide selectivity range can seamlessly reproduce existing HPLC methods and simultaneously provide a pathway to UPLC compatibility for the future.

In addition, the ability for Alliance HPLC to seamlessly integrate with customers’ existing Empower software network for instrument control and data processing significantly expands the impact of the system. Empower 3 Software, which is Waters’ flagship chromatography data software, makes it easier to run samples and produce results without extensive training, re-engineering workflow, or adding new software to support instruments or advanced chromatographic techniques.

Analytical laboratories depend on the Alliance HPLC System to meet the rigorous requirements ranging from routine analyses to the performance standards of new-product research and development. Whether a lab specializes in pharmaceutical, chemical, food safety, environmental, or quality control analyses, the Alliance HPLC system offers integrated solvent and sample management to ensure consistent system-to-system performance and high reproducibility.

Since the Alliance HPLC features an Automated Solvent Compressibility, the users do not have to select from calibration or look-up tables, and risk accidental errors in selection.
