The Waters Natural Products Application Solution with UNIFI provides a bottleneck breakthrough solution for analyzing natural products. Built around the UNIFI Scientific Information System, it converts traditionally labor intensive and cumbersome multistep sample profiling procedures into a workflow-driven and significantly streamlined process. It incorporates a unique Traditional Medicine Library into the workflow, along with automatic fragment ion confirmation implementation. As a result, the process of ingredient profiling can move from data acquisition to review of a completed analysis with the click of a button. The solution also provides users with test samples, user-required analytical method templates, and comprehensive workflow templates. All is managed into an easy-to-use solution that minimizes technical requirements for analysts.
