Agilent CrossLab Functional Verification service delivers cost-effective proof of maintenance and calibration for a range of analytical instruments. Nonpharmaceutical analytical laboratories—such as food safety, forensics, or nutraceuticals—often work under ISO 17025 guidelines or similar quality accreditation. Functional verification starts with factory-recommended maintenance of your Agilent LC, GC, GC/MS, and spectroscopy systems, to ensure optimal performance. Next, metrology-based testing confirms the accuracy and calibration of critical functions. We also offer functional verification for non-Agilent LC and GC systems.
