For customers who need the ultimate in sensitivity, reproducibility, and speed, the ACQUITY PREMIER LC-MS provides the best sensitivity and peak shape for analytical separations. When High Performance Liquid Chromatography (HPLC) wasn't keeping pace with your demands to analyze more samples, faster, and with better results, Waters introduced ACQUITY UPLC, which advanced speed, resolution, and sensitivity in chromatography. As your lab requirements continued to rapidly evolve, our technology has advanced to help you meet them. Our ACQUITY PREMIER Solution is the most significant innovation in separations science in more than 15 years, designed to reduce variability associated with metal sensitive analytes - without time-consuming tasks like system and column passivation. Based on your input, ACQUITY PREMIER was developed to help solve some of the most complex challenges associated with unpredictable chromatography, to meet the needs of today and evolve to meet the needs of tomorrow.
