Patent number: 9074250Abstract: Cartridges for the isolation of a biological sample and downstream biological assays on the sample are provided, as are methods for using such cartridges. In one embodiment, a nucleic acid sample is isolated from a biological sample and the nucleic acid sample is amplified, for example by the polymerase chain reaction. The cartridges provided herein can also be used for the isolation of non-nucleic acid samples, for example proteins, and to perform downstream reactions on the proteins, for example, binding assays. Instruments for carrying out the downstream biological assays and for detecting the results of the assays are also provided.Type: GrantFiled: February 5, 2013Date of Patent: July 7, 2015Assignee: Luminex CorporationInventors: Dylan Hilmer Bird, Jesus Ching, Bruce A. Johnson, Keith E. Moravick, Bruce Richardson

Patent number: 9034651Abstract: This invention relates to methods and apparatus for determination of ion concentrations, particularly in downhole water from hydrocarbon wells, aquifers etc. It is useful in a wide range of applications, including predicting the formation of scale and fingerprinting waters from different sources. More particularly, the invention relates to the use of ligands whose electronic configuration is altered by the binding of the scaling ions within a water sample. These alterations are detected electrochemically by applying varying potential to electrodes and measuring current flow as potential is varied, from which is derived the concentration of scaling ions in the fluid.Type: GrantFiled: June 22, 2010Date of Patent: May 19, 2015Assignee: Schlumberger Technology CorporationInventors: Li Jiang, Timothy Gareth John Jones, Andrew Meredith, Markus Pagels, Amilra Prasanna De Silva
