Wiley releases the 2026 Wiley Registry/NIST Mass Spectral Library, expanding its GC-MS reference collection to more than 1.2 million validated EI mass spectra.

Learn how NIST MS Search stores library search history, what HLM files are used for, and how to automatically remove temporary files to keep your workspace clean and organized.

Discover what the NIST Identification Folder contains during low-resolution EI GC-MS processing. Learn how TIC, ELU, FIN, TSV, RUN, and LOG files support deconvolution and library searching.

Wiley has released the NIST/EPA/NIH EI Mass Spectral Library 2026 and NIST MS/MS Spectral Library 2026, featuring expanded spectral collections, updated search software, and separate EI and MS/MS products.

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 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.

Discover what’s new in Clarity 10.2, including expanded instrument control support, enhanced MS data import/export capabilities, and important changes to hardware compatibility.

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.

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 to process accurate-mass GC-MS data in NIST 26 using integrated deconvolution, library searching, MS Interpreter validation, filtering tools, and Excel reporting workflows.
