February 2012 The database has been updated: twice as many compounds as before (now over one quarter million compounds). In addition, the number of synonyms for each compound is listed in the printouts. Search time remains at about 5 seconds. August 2011 At ASMS 2011, several mass spectrometrists who stopped by our booth asked for more detail on our database design and how our database can be searched. One of our US patent applications (Publication Number 20110171619) published on the USPTO website on July 14th, and this document goes into great detail. December 2010 Rational Numbers Search 3.1 has been launched.
The database has been expanded over 30% to a total of 132277 compounds found in commerce. Typical search time is still less than 2 seconds. July 2010 Rational Numbers Search 3.0 has been launched.
This new version is much faster and easier to use. Contact us for
