We are actively working on improving the ADAP-KDB website and adding new features and updates every Sunday, 1pm - 11pm GMT. You may experience interruptions in the website work during that period.

ADAP-KDB Spectral Knowledgebase

Welcome to ADAP-KDB Spectral Knowledgebase!

ADAP-KDB is a compound and mass spectra search engine. You can use it to Identify and prioritize spectra.

Use this web app to search query spectra against both private and public compounds and mass spectra.

Use it to prioritize both known and unknown mass spectra.

Use it as a search engine to identify spectra from libraries.
