- You can now receive the HighResNPS database with predicted retention times specific to your LC method. That’s retention times for over 1800 compounds!

- The HighResNPS August 2020 libraries are almost ready to be downloaded from The HighResNPS consensus libraries will be available in the following formats: Agilent MassHunter (.cdb), Sciex (.lpb), Bruker TASQ (.csv) and Bruker DataAnalysis (.csv), Waters UNIFI (.ulc), Thermo TraceFinder (.cdb + inclusion list), Progenesis QI (.sdf + .msp), Structure Data File (.sdf) and Excel (.xlsx)). The libraries contain 1862 compounds. 1074 of the compounds have fragment data.

Did you know...
- We will never agree on the NPS name, the SMILES string or the IUPAC name, but we can always agree on the InChIKey

- Duplicate NPS entries are welcome on HighResNPS. They help to self-validate the database and are used to make the “Consensus and unique” library. Ideally there should be 3 or more entries on each NPS.

- The webpage can be very helpful for generating InChIKeys and SMILES
Can anyone provide the HRMSMS fragment data for:

- MDPHiP 1-(1,3-benzodioxol-5-yl)-4-methyl-2-pyrrolidin-1-yl-pentan-1-one

HighResNPS is a crowd-sourced mass spectral database for HR-MS screening of New Psychoactive Substances (NPS).

The database can be used for direct searches on compound names and exact mass of precursor and/or fragment ions.
Also, the database can be downloaded and converted to a suspect library for Agilent QTOF MS, Bruker QTOF MS, Waters QTOF MS, Sciex QTOF MS or Thermo Orbitrap MS. currently contains more than 3200 entries (where more than 1800 entries are unique). is only intended for a closed user group and not open to the general public.
