Patent number: 7960178Abstract: A sample processing system 101 that may be automated and methods are disclosed where sample(s) 198 are arranged on a carrier element 197 and a process operation control system 171 automatically processes the sample(s) perhaps robotically according to an desired aggregation of event dictated by an input 173. Alteration of an initial aggregated event topology may be accepted while the system is processing an initial aggregation and varied-parameter robotic control simulation functionalities 606 may be accomplished to determine an enhanced sequence for processing. Suggested operator actions may be displayed that might further enhance the scheduling of the altered aggregated event topology together with an automatic operator need prompt 608 that may inform an operator of a need for a particular action in order to accomplish the desired tasks.Type: GrantFiled: December 19, 2003Date of Patent: June 14, 2011Assignee: DAKO Denmark A/SInventors: Marc Key, Gordon Feingold, Rosanne Welcher

Patent number: 7960179Abstract: Analytical methods using hydrogen/deuterium exchange are provided which reduce or eliminate the back-exchange of deuterium for hydrogen. The methods, which are useful in protein and peptide mapping, include the steps of (a) providing a peptide or protein comprising a solvent accessible hydrogen; (b) exchanging the solvent accessible hydrogen for a deuterium; (c) separating the peptide or protein with supercritical fluid chromatography; and (d) analyzing by mass spectrometry the mass of the separated peptide or protein. Supercritical fluid chromatography enables the observation of fast exchanging hydrogen atoms missed using conventional liquid chromatography methods.Type: GrantFiled: October 12, 2009Date of Patent: June 14, 2011Assignee: Florida State University Research FoundationInventors: Mark R. Emmett, Sasa Kazazic, Alan G. Marshall, Michael J. Greig

Patent number: 7960180Abstract: Methods and apparatus to capture and release microbe particles using amino-functionalized silica substrates are described. An example apparatus adapted to capture a microbe particle includes a silica substrate and a positively charged material to at least partially coat the silica substrate. The positive charged material includes an aminopropyl functional group.Type: GrantFiled: February 19, 2008Date of Patent: June 14, 2011Assignees: University of Notre Dame Du Lac, Scientific Methods, Inc.Inventors: Hsueh-Chia Chang, Zilin Chen, Fu-Chih Hsu, David Battigelli

Patent number: 7960181Abstract: The invention relates to methods of determining potassium ions in a sample, wherein the ions are contacted with a compound having chromophoric moiety and an ionophoric moiety, where the ionophoric moiety interacts with the potassium ions present in the sample, resulting in the chromophoric moiety changing its radiation absorption properties in the ultraviolet and visible regions of the spectrum. For example, a change in an intensity of an absorption maximum is measured and the ion concentration is determined accordingly.Type: GrantFiled: May 2, 2007Date of Patent: June 14, 2011Assignee: OPTI Medical SystemsInventors: Huarui He, Chao Lin, Neeta Raje, Chuseng Liu
