ONKI3 | Medical Subject Headings

The ONKI is provided as a part of the ONKI Living Lab - an open lab for testing the latest semantic web technologies in practice, with real users like you. Currently, over 10 000 people are using ONKI each month.

We hope you like the ONKI service and enjoy using it for your purposes!

If you encounter any problems or have improvement ideas, please contact the ONKI team. We are also very much interested in your success stories in using ONKI - please share your experiences!

Scope note:	A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis.
