The software program includes instructions for the processor to correlate ... 11/02/06 - 20060245975 - Adsorbent housing with separated adsorption outflow and desorption inflow A system for pre-concentrating analytes in a sample prior to introduction into a chromatographic column is generally disclosed comprising a housing, an adsorbent disposed in the housing, and first and second conduits having an inlet and an outlet, respectively, for transferring fluid out of and into the housing during adsorption/dry ... 10/05/06 - 20060222568 - Miniature chemical analysis system An apparatus, according to one aspect, may include a chromatograph and a bulk acoustic resonator. The chromatograph may include a channel that is defined at least partially in a monolithic substrate. The channel may have an inlet to receive a sample and an outlet. A chromatography material may be included ... 09/21/06 - 20060210437 - Sugar chain analyzing apparatus Different lectins are immobilized in four columns, respectively. A sample containing a sugar chain is injected from a sample injection section, sent to one of the columns through a first flow path switching valve and a second or third flow path switching valve. Then, an eluate of the column is ... 08/31/06 - 20060193748 - Integrated lc-esi on a chip A microfluidic system with on-chip pumping which can be used for liquid chromatography and also electrospray ionization mass spectrometry and which provides improved efficiency, better integration with sensors, improved portability, reduced power consumption, and reduced cost. The system can include (A) a main chip comprising: a substrate having a front ... 08/24/06 - 20060188397 - Method and apparatus for fraction collection The present invention provides a method and apparatus for fraction collection from a chromatographic system. One or more substances of interest from a sample are collected in high concentration with high efficiency. ... 07/06/06 - 20060147344 - Fully packed capillary electrophoretic separation microchips with self-assembled silica colloidal particles in microchannels and their preparation methods A novel CEC column preparation method for various forms of CEC separation using selectively or fully packed microchannels with self-assembled silica colloidal particles is disclosed. The method relies on the three dimensional uniform silica colloidal packing through selective regions or whole channels resulting in uniform EOF and reproducibility. The fully ... 05/04/06 - 20060093521 - Method and apparatus for monitoring processes using a single detector Embodiments of the invention feature methods and apparatus for the efficient utilization of detectors and other components.
