| 20100236324 | COLUMN TIP PROCESSING DEVICE AND COLUMN TIP PROCESSING METHOD - The present invention relates to a column tip processing device and a column tip processing method, and its objective is to enhance the contact between a packing and a fluid as a subject to be processed whereby accomplishing a highly efficient reaction as well as an accurate processing, which has a nozzle head having a single or multiple-channeled nozzle, a suction and discharge mechanism, one or more types of column tips in which a packing is enclosed, a stage provided with a fluid housing part group including a plurality of fluid housing parts in which various solutions are or can be housed, and moving means for moving the nozzle head relatively to the fluid housing part group, and also has a controlling part which controls the suction and discharge mechanism and the moving means with regard to quantities, pressure, flow rate, the number of cycles, time or position of the suction or discharge by the nozzle based on a structural requirement relating to the structure of the one or more types of column tips to be fitted to the nozzle and a processing requirement relating to the processing contents involving one or more types of subject fluids subjected to the suction or discharge of the column tips. | 09-23-2010 |
| 20120304746 | THERMAL-BASED FLOW SENSING APPARATUSES AND METHODS FOR HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY - One aspect of the invention provides a flow sensing apparatus including: a fluid channel that allows a fluid to flow in a first direction; a first thermoelectric sensing element arranged at a first position along the fluid channel such that it senses a temperature of the fluid; a second thermoelectric sensing element arranged at a second position along the fluid channel and separated from the first sensing element by a predetermined distance along the fluid channel; and a heating element arranged between the first and second thermoelectric sensing elements, the heating element being equally spaced from the first and second thermoelectric sensing elements. | 12-06-2012 |
| 20130014569 | THERMAL-BASED FLOW SENSING APPARATUS AND METHOD FOR HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY - One aspect of the invention provides a flow sensing apparatus for sensing fluid flow in a nano-scale high-performance liquid chromatography apparatus. The flow sensing apparatus includes: a fluid channel that allows a fluid to flow in a first direction; a first infrared sensor arranged at a first position along the fluid channel such that it senses a temperature of the fluid; a second infrared sensor arranged at a second position along the fluid channel and separated from the first sensor by a predetermined distance along the fluid channel; and a heating element arranged between the first and second infrared sensors. The heating element is equally spaced from the first and second infrared sensors. | 01-17-2013 |
| 20130139574 | Devices for heating and cooling a capillary liquid chromatographic system - Devices for heating and cooling chromatographic columns, transfer tubing, fittings and accessories and can also be placed next to the mass spectrometer's inlet region are disclosed. These devices have the advantage of allowing the user to dramatically reduce the post-column dead-volume while using the heating or cooling devices, a necessity for low-flowrate liquid chromatography. These devices also do not require the user to heat or cool the entire column with fittings to achieve optimized benefits for chromatography. | 06-06-2013 |
| 20140150536 | COLUMN MANAGER WITH A MULTI-ZONE THERMAL SYSTEM FOR USE IN LIQUID CHROMATOGRAPHY - A thermal system for use in a column manager of a liquid chromatography system comprises a plurality of spatially separated individually controlled thermoelectric chips. A column module houses a plurality of thermally conductive troughs. Each trough resides in a separate thermal zone to be thermally conditioned individually by one of the individually controlled thermoelectric chips. Each trough is adapted to hold one or more liquid chromatography columns therein. A plurality of spatially separated thermal bridges includes a first thermal bridge thermally coupling one of the thermoelectric chips to a first one of the plurality of troughs and a second thermal bridge of the plurality of thermal bridges thermally coupling another of the thermoelectric chips to a second one of the plurality of troughs. | 06-05-2014 |
