Chain of Custody
Chain of Custody in an Environmental LIMS: Evaluate the Record, Not the Demo
Use a sample-based evaluation to test whether a LIMS can preserve and reconstruct the custody record your environmental work requires.

Environmental Testing
Evaluate environmental laboratory work from sample receipt and custody references through method context, QC review and customer deliverables. These guides cover water-testing LIMS, detection limits, PFAS readiness and reporting interfaces using cited sources and laboratory-defined acceptance criteria. Use the receipt checklist to identify fields, timestamps, exceptions and responsibilities; verify external formats and submissions for the intended program.
