NIST23 Retention Data (NIST23-RO)
The NIST23 (2023) mass spectral library, the successor of the NIST20/17/14, is a fully evaluated collection of electron ionization (EI) and MS/MS mass spectra, with chemical and GC data, plus search software to identify your own unknown spectra. It is a product of a more than three decade, comprehensive evaluation and expansion of the world’s most widely used mass spectral reference library by a team of experienced mass spectrometrists at the National Institute of Standards and Technology (NIST) in which each spectrum was examined for correctness.
This version (NIST23-RO) includes retention data only.
