4.7 Library Validation
4.7.1 Introduction
Library validation is an important step in the process of qualitative method development. It evaluates
the suitability of a library for use in Routine Analysis. The test determines whether all samples were
correctly assigned to their corresponding products, detects conflicting products, and helps to
establish correct thresholds. This test is essential in identification and is important for qualification as
well.
During the validation process, Vision processes all library spectra. Each spectrum is run through all
existing library methods, clustering, identification, and qualification. If any of the methods does not
exist, Vision will bypass the test and the N/A (not applicable) statement will appear in the proper
place on the validation report.
