In order to capture and manage the wealth of analytical information that is generated from powerful chromatographic separations and high resolution mass spectrometry (HRMS) screening experiments, Waters has created the UNIFI® Scientific Library. UNIFI provides an unparalleled platform for the compilation of valuable experimental information. Once a compound is added to the library, relevant reference and classification information can be added within the software. With the emergence of novel pesticides, metabolites, and other contaminants, the ability to create additions to UNIFI`s scientific library is a powerful tool to ensure confident identifications in future screening experiments.
