Bio-Rad Laboratories KnowItAll software version 9.0

Bio-Rad Laboratories has announced an unlimited spectral range and resolution feature in version 9.0 of its KnowItAll software.

KnowItAll 9.0 allows users to store spectra in a user database at the precise range and resolution at which each spectrum was measured rather than being forced to conform to a fixed range and resolution for the entire database. As a result, users have more control over their data and can perform more accurate spectral searches that compare experimental spectra to reference databases.

Researchers use spectral search software to identify unknown substances and verify the composition of synthesised materials in a number of applications and industries. First, precision instruments measure a substance and produce a spectrum, which is expressed as a graph showing a series of peaks and valleys that is specific to the sample material. That spectrum is then compared with a database of the measured spectra of known substances. If a matching spectrum is found, the material in question can be identified. Bio-Rad’s KnowItAll solutions provide search software tools, as well as the world’s most extensive collection of reference spectra used in this type of analysis.

Technological advances have changed disk space and computational time limitations of computer search methods, making possible major advances in spectroscopic computing. Removing constraints on spectral data is critical to those who perform spectral searches or store spectral data, since altering an original spectrum’s resolution has a significant impact on search results. With KnowItAll 9.0, researchers can preserve the integrity of their spectral databases.

Additional features in the software release include independent management of properties from multiple analytical techniques in user databases; simplified database creation; structure drawing tools comply with IUPAC structure drawing guidelines; and higher resolution spectra in HaveItAll IR, NIR, Raman database subscriptions.
