The National Institute of Standards and Technology has announced that it will be releasing the NIST 26 version of the Mass Spectral Libraries in June, 2026. The libraries (EI, MS/MS) are now sold and distributed as separate standalone individual libraries. The Retention Index (RI) library is included with the EI library, but is also sold as a separate standalone library.
EI/RI Library Details: NIST26-flyers EI
Tandem (MS/MS) Library Details: NIST26-flyers Tandem
You can pre-order the NIST 26 Libraries prior to the release and optionally receive the NIST 23 libraries in advance of the release. The NIST 26 versions of the libraries will be delivered upon release in June.
We will also continue to sell the NIST 23 Libraries at current prices through the end of September, 2026.
See the announcement on our NIST Libraries page for more information and to pre-order the NIST 26 Library.
