Learn how to use MS Interpreter in NIST 26 to interpret accurate-mass EI GC-MS spectra, verify library hits, compare candidate structures, and improve compound identification.

Learn why measurement uncertainty is essential for interpreting analytical results, making reliable decisions, comparing laboratory data, and ensuring compliance with modern testing standards.

Discover why LC–MS/MS and GC–MS/MS continue to expand across regulated laboratories, driven by biopharma, PFAS regulations, AI-powered workflows, and advances in sample preparation.

Learn how to create retention index calibrations in NIST 26, calculate RI values automatically, and improve GC-MS compound identification by combining spectral library searching with retention indices.

Learn how interlaboratory comparisons (ILCs) other than proficiency testing differ from PT schemes, their intended purposes, limitations, and how they support ISO/IEC 17025 compliance.

Learn how NIST 26 Hybrid Search expands EI GC-MS library searching by identifying structurally related compounds using mass-shifted fragment matching, DeltaMass analysis, and MS Interpreter validation.

Interlaboratory comparisons, proficiency testing, ring tests, and round robins are often confused. Learn the correct terminology, key differences, and the importance of harmonized language in quality assurance.

PFAS are among the most persistent environmental contaminants. Explore LC-MS/MS, GC-MS, TOF, and HRMS approaches for PFAS detection, identification, and quantification.

Learn how to use NIST 26 Lib Search with spectra sent from the Chromatogram Window, compare Full Spectrum and Reverse searches, and improve EI GC-MS identifications.

Learn how proficiency testing providers assign reference values, estimate uncertainties, calculate performance scores, and interpret z, zeta, En, and percentage difference results.
