摘要： An adjustment channel is connected to first and second pump mechanisms in parallel therewith. The flow of a liquid sent by pump heads is split, and part of the liquid is sent to an outlet port side, while the remaining liquid flows through the adjustment channel and is returned to an inlet port side. The adjustment channel has a restrictor which is so arranged that the flow rate is set to 100 μL/min to 1 mL/min, and pressure of 2 MPa to 20 MPa or thereabouts is applied thereto. In micro LC and nano LC, the flow rate of a column is 100 nL/min to 10 μL/min or thereabouts, and pressure of several MPa to 20 MPa or thereabouts is applied. Therefore, of the liquid sent from the pump mechanism, 0.1% to 1% is delivered from the outlet port, while the remaining liquid flows through the adjustment channel and is returned to the inlet port side.

In the sample introduction device, when a high pressure valve 51 is switched from a load status to an injection status in a total volume injection method, the communication between a stator hole d in communication with an injection port 25 and a stator hole c connected to a flow path toward a separation/detection section 30 occurs earlier than the communication between a stator hole b in communication with a liquid feeder 10 and a stator hole a in communication with a needle 54. A length of a rotor groove Y communicating stator holes d and e or stator holes d and c is set longer than a length of another rotor groove X.

摘要： A distal end portion of a probe has a multi-pipe structure, in which an effluent solution from a high speed liquid chromatography passes through an innermost flow passage, a matrix solution through an outer flow passage, and the air through an outermost flow passage. A distal end of the outermost pipe extends 1.2 mm longer than the distal end of the inner duplex tube to form a liquid reservoir. When dropping a liquid droplet from the distal end of the probe, the air is blown out to expel the liquid gathered in the liquid reservoir to be dropped.

摘要： A sample is introduced from an injector unit into a mobile phase. One target component is separated into a plurality of vials by a fraction collector. Next, a sampler sequentially suctions the eluate from the plurality of the vials and performs an LC analysis on each of the eluate portions, thereby producing a chromatogram. A peak detector calculates the peak area corresponding to the amount of the target component in each chromatogram. A delay estimator extracts the peak area in the fraction having the maximum peak area and the peak areas in the previous and succeeding fractions on the time axis of the foregoing fraction. Then, the delay estimator estimates a delay volume from a detector to the tip end of the dispenser nozzle based on data such as the peak areas, the flow rate of the liquid fed from the pump, positions of the vials, and the position of the peak of the target component in the chromatogram detected by the detector, and stores the delay volume. Upon preparative separation of a desired component, a delay time is calculated based on the delay volume and the flow rate and the timing for the preparative separation is controlled based on the delay time.

摘要： Herein disclosed is a new internal combustion engine which is operable on a fuel which is combusted with the agency of an oxidizing gas containing hydrogen peroxide or oxygen gas so that exhaust gases emitted from the engine contains no nitrogen oxides in the absence of the element nitrogen in the oxidizing gas. Where the hydrogen peroxide in particular is utilized, the hydrogen peroxide exothermically decomposes into a hot mixture of water and oxygen so that the fuel is combusted at a high temperature so that the exhaust gases are clear of not only the nitrogen oxides but unburned hydrocarbons and carbon monoxide. Since no air is used as the oxidizing gas for the fuel, the internal combustion engine is suitable for use in operations in those environments in which air is extremely thin although the engine can be successfully incorporated in various power driven vehicles.

摘要： A sample introduction method for reducing carry-over is provided. After a sample introduction device in a total volume injection method draws a proper amount of a sample solution from a sample container and further draws a solution with the same composition as a mobile phase solution with a needle 24, the needle 24 is inserted into an injection port 25. When flow paths are switched to communicate a liquid feeder, a sample loop 23, the needle 24, the injection port 25, and a separation/detection section, the solution with the same composition as the mobile phase solution is forced into a gap between the injection port 25 and the needle 24. Therefore, the samples squeezed out of a tip section of the needle 24 during the switching of the flow paths are prevented from being forced into the gap between the needle 24 and the injection port 25.
