| 20090049891 | Supercritical-Phase Mixed Chromatography Method and Installation for Implementing Same - A method for the superficial-phase chromatography of a product comprises the steps which are performed continuously in the following order, namely: an operation consisting in pumping a supercritical fluid; and operation consisting of injecting at least one sample of product into at least one chromatography column, a detection operation, and a fraction collection operation. The method comprises at least a first diversion along between an analytical channel and a preparatory channel, which diversion is performed prior to the supercritical fluid pumping operation and the analytical and preparatory channels each including respective supercritical fluid pumping operations. The method is also characterized in that the collection operation is common to both the analytical and preparatory channels. An installation used to implement one such method is described. | 02-26-2009 |
| 20110179852 | Molecule Detection Device Formed in a Semiconductor Structure - Semiconductor devices, chromatography devices and integrated circuits for detecting one or more molecules and methods for forming a semiconductor device for detecting one or more molecules are presented. For example, a semiconductor device for detecting one or more molecules includes a channel formed within a semiconductor structure, and at least one detector formed within the semiconductor structure. The at least one detector detects the one or more molecules in the channel The semiconductor device may optionally comprise one or more additional channels formed within the semiconductor structure. The semiconductor device may, for example, be operative to detect a single molecule. | 07-28-2011 |
| 20110197654 | System and Method for Fluid Sample Analysis - A LASER based system for analysis of fluids utilizing frequency shift analysis. In the preferred embodiment of the invention, the liquid for analysis is reduced to a gaseous state so that it can be injected into an extended LASER cavity, so as to detect minute frequency shifts caused by the various gases in the cavity via sensors associated with the cavity. The present invention thereby provides stable detection system, with microprocessor-based electronics, which can be used to provide analyses of the gases, and thus the input liquids and its markers. | 08-18-2011 |
| 20130192339 | COMPOSITE SAMPLING OF FLUIDS - Composite sampling of a fluid flowing through a conduit includes collecting, in a vessel coupled to the conduit through which the fluid is flowing, a first discrete sample of fluid from the conduit, the first discrete sample having a first selected volume, and collecting, in the vessel and at a first interval from the first sample, a second discrete sample of the fluid from the conduit, the second discrete sample having a second selected volume, thereby forming a composite sample in the vessel while the vessel is coupled to conduit. The composite sample includes the first discrete sample and the second discrete sample, and may include one or more additional discrete samples. An apparatus for collecting the composite sample includes a gas chromatograph, and is arranged such that the composite sample is provided to the gas chromatograph without removing the composite sample from the apparatus or transporting the composite sample. | 08-01-2013 |
| 20140238107 | REAL-TIME ON-SITE GAS ANALYSIS NETWORK FOR AMBIENT AIR MONITORING AND ACTIVE CONTROL AND RESPONSE - Embodiments of an apparatus comprising a plurality of multiple-gas analysis devices positioned within a relevant area, each multiple-gas analysis device capable of detecting the presence, concentration, or both, of one or more gases. A data and control center is communicatively coupled to each of the plurality of multiple-gas analysis device, the data and control system including logic that, when executed, allows the data and control center to monitor readings from the plurality of multiple-gas analysis devices and if any readings indicate the presence of one or more contaminants, identifying the source of the contaminants based on the readings from the plurality of multiple-gas analysis devices. | 08-28-2014 |
| 20150323508 | COMPOSITE SAMPLING OF FLUIDS - Composite sampling of a fluid flowing through a conduit includes collecting, in a vessel coupled to the conduit through which the fluid is flowing, a first discrete sample of fluid from the conduit, the first discrete sample having a first selected volume, and collecting, in the vessel and at a first interval from the first sample, a second discrete sample of the fluid from the conduit, the second discrete sample having a second selected volume, thereby forming a composite sample in the vessel while the vessel is coupled to conduit. The composite sample includes the first discrete sample and the second discrete sample, and may include one or more additional discrete samples. An apparatus for collecting the composite sample includes a gas chromatograph, and is arranged such that the composite sample is provided to the gas chromatograph without removing the composite sample from the apparatus or transporting the composite sample. | 11-12-2015 |
