| 20080219890 | SAMPLE LOADING AND RECOVERY - A apparatus and method for loading a sample into a microfluidic flow cell allows for more precise loading, reduced cross-contamination, and more efficient use of samples to be analyzed. The system for loading a sample into a flow cell includes a flow cell defining a plurality of individually isolated channels through which fluid can flow. The flow cell also defines an inlet port and an outlet port for each of the channels. The system also includes a base that defines a chamber for receiving the flow cell, a cover pivotally attached to the base, and a passive vacuum source for pulling a volume through the flow cell. The method of loading a sample includes inserting the flow cell into the sample loading apparatus, placing a sample in at least one of the wells of the loading block, activating a vacuum source fluidly coupled to the outlet ports to pull the sample into the channel, and optionally aspirating the unused sample from the well. | 09-11-2008 |
| 20080240994 | Liquid aspirating tube, liquid dispensing apparatus and liquid dispensing method - The present invention is to present a liquid dispensing apparatus which is capable of preventing contamination by previously aspirated liquid, even when residual liquid in a pipette tip separated from the dispensing apparatus is scattered. The liquid dispensing apparatus includes: sample dispensing arm | 10-02-2008 |
| 20100119415 | DISPENSING DEVICE AND AUTOMATIC ANALYZER - A dispensing device includes a probe that suctions and discharges liquid contained in a vessel; a probe control unit that moves the probe downward in a stepwise fashion by a predetermined amount by controlling a lowering operation of the probe to an inside of the vessel and controls a suction operation and a discharge operation of the probe in each step; a pressure detecting unit that detects a pressure in the probe; a suction-and-discharge-state judging unit that judges a suction state or a discharge state of the liquid by the probe based on a detection result by the pressure detecting unit; and a liquid-surface detecting unit that detects a liquid surface position of the liquid based on a lowering amount of the probe when the suction-and-discharge-state judging unit judges that the probe suctions the liquid or the probe discharges the liquid. | 05-13-2010 |
| 20110116973 | SAMPLE SEPARATION DEVICE WITH VALVE - A sample separation device for separating a sample comprises a first fluid supply path for supplying a first fluid, a second fluid supply path for supplying a second fluid, a sample separation unit adapted for separating the sample, a sensor configured for determining a value of a parameter related to the fluid, and a valve configured for selectively coupling both of the first and second fluid supply paths to the sensor and to the sample separation unit, or coupling one of the first and second fluid supply paths to the sensor. | 05-19-2011 |
| 20130121880 | AUTOMATIC ANALYZER - Dispensing failure occurs when air-sucking or clogging is caused at the time of sucking sample or reagent by using a dispensing probe. An automatic analyzer is equipped with a dispensing mechanism ( | 05-16-2013 |
| 20130323126 | FLUID SENSING AND CONTROL IN A FLUIDIC ANALYZER - Instrument-cartridge interfaces for fluidic analyzers that have an instrument and a removable cartridge are disclosed. For example, and in one illustrative embodiment, the instrument may include a needle that is adapted to penetrate a septum on a removable cartridge. In another illustrative embodiment, the instrument may include a plunger that is adapted to deform a deformable membrane on a removable cartridge. In yet another illustrative embodiment, the instrument may include a nozzle that is adapted to mate and seal with a flow channel on a removable cartridge. Techniques for detecting the flow rate in a flow channel on a removable cartridge, as well as the position of fluid in a flow channel of a removable cartridge, are also disclosed. | 12-05-2013 |
| 20140037503 | AUTOMATIC ANALYZER - The present invention performs cleaning on the inner and outer surfaces of a dispensing nozzle without reducing the processing speed of a device. To achieve the object, a feature of the invention is that a dispensing nozzle rinse tank includes a rinse liquid supply port. More specifically, by suctioning rinse liquid from the rinse liquid supply port provided on the dispensing nozzle rinse tank and discharging the rinse liquid into the rinse tank, the inner and outer surfaces of the dispensing nozzle can be rinsed in a short amount of time. According to the invention, it is only required that a rinse liquid supply port be provided on the dispensing nozzle rinse tank, the structure is simple. Moreover, because the inner and outer surfaces of the dispensing nozzle can be rinsed in a short amount of time by shortening the movement distance of the dispensing nozzle, analyses can be performed without reducing the processing speed of the device. | 02-06-2014 |
| 20160038934 | FLUID ANALYSIS CARTRIDGE AND FLUID ANALYSIS APPARATUS HAVING THE SAME - A fluid analysis apparatus including: a fluid analysis cartridge comprising a fluid supplying part configured to supply a fluid sample; and a pressing member configured to press and seal the fluid supplying part, wherein the pressing member is configured to couple with the fluid analysis cartridge so that the fluid supplying part is inserted into the pressing member. | 02-11-2016 |

| 20100196205 | FLUIDIC CONFIGURATION FOR FLOW INJECTION ANALYSIS - A fluidic configuration, both structural and methodological, for the injection of sample greatly reduces dead volume allowing rapid transition to 100% sample in a flow cell. For a continuous flow injection analysis system the structure and method provide counter flows to remove in one direction the dispersed region of the sample to waste before injecting non-dispersed sample into the flow cell by reversing the effective flow direction. The injection point itself is directly adjacent to the flow cell where all channels are microfluidic channels. Therefore, only the flow cell volume needs to be displaced during injection of sample in order to achieve 100% transition to sample within the flow cell. This greatly accelerates the rise and fall times thereby extending the kinetic range of the real-time interaction analysis instrument. In addition such rapid transition to sample improves overall data quality thereby improving kinetic model fitting. | 08-05-2010 |
