A chromatograph system with improved automation is provided. In the chromatograph system of one embodiment, a regression line is set between retention times of predetermined peaks measured at each run in the past for a standard sample having known components. Referring to this regression line, the peak identifying condition, i.e., time window, is corrected. In another embodiment, there is provided a chromatograph apparatus having a function of estimating a limited life time of a system component. The analyzed results of the chromatograph system can thus be improved.
摘要:
The present invention relates to a chromatography analysis method and a system employing the same which are capable of automatically determining an constituents to be detected contained in the unknown sample based on results on measuring a standard sample. The standard sample is first separated to obtain its chromatogram. The system extracts the necessary information from the chromatogram to identify the peaks corresponding to the constituents to be detected to set widths of time windows for the peaks. Then, the time windows thus set are applied to the chromatograms obtained by the separation of the unknown sample to identify the constituents contained in the unknown sample. By employing the present invention, it is unnecessary for an operator to input the retention time of each constituent to the system.
摘要:
Physiologically active substances contained in a biological sample not subjected to deproteinization can be converted to their derivatives at a high efficiency without being adversely affected by the protein present in the sample, and accordingly the analysis of said physiologically active substances in the form of said derivatives can be performed at a high precision.

The present invention provides a liquid chromatographic analyzer for analyzing a sample containing components for analysis by reacting the sample with a pre-labeling reagent to obtain a reaction mixture containing labeled components, concentrating the reaction mixture and separating the labeled components from each other, and detecting the separated labeled components by a detector, the steps of analysis being controlled to concurrently proceed by a control unit, thereby shortening the time for analysis per sample which analyzer includes: (a) a unit for storing samples containing components for analysis and a pre-labeling reagent for the components at a constant temperature, (b) a unit for reacting the sample with the pre-labeling reagent at a constant temperature to obtain a reaction mixture containing labeled components, (c) a unit for transferring one of the samples and the pre-labeling reagent from unit (a) to unit (b), (d) a unit for concentrating the reaction mixture and separating the labeled components from each other, (e) a unit for detecting the separated labeled components, and (f) a unit for controlling the steps of analysis to concurrently proceed, thereby shortening the time for analysis per sample.
摘要:
In a magneto-optical eraser, information recorded on a magnetic layer of a magneto-optical recording medium is erased or initialized by applying light over the magneto-optical recording medium from a light source (13,43) in a reflector to heat the magneto-optical recording medium and also by supplying a magnetic field to the magneto-optical recording medium along its axis of easy magnetization. In one form, a plurality of light sources (13) may be disposed in the surface of a single reflector (12). Alternatively, the magneto-optical recording medium may be double-faced, and a light source and reflector may be disposed on each side of the double-face recording medium. A pre-heater (52) may increase the temperature within a glass housing (50,51) to a temperature less than the softening point of the medium substrate.

A magneto-optical recording medium including a first magnetic layer (having film thickness t1 and saturation magnetization Ms1) and a second magnetic layer (having film thickness t2 and saturation magnetization Ms2) which are respectively made from a rare earth-transition metal alloy and sequentially laminated on a substrate to jointly make up a recording layer. Only the first magnetic layer or both the first and second magnetic layers contain a light rare earth element. At room temperature, a transition-metal sub-lattice magnetic moment is dominant in the first magnetic layer, whereas a rare earth sub-lattice magnetic moment is dominant in the second magnetic layer, respectively. Substantially, the directions to stabilize magnetization of the first and second magnetic layers are inverse from each other and the expression shown below is satisfied.t1.times.Ms 1-t2.times.Ms2.ltoreq.5 (.mu.m.times.emu/cm.sup.3)
摘要:
A front frame structure for a vehicle has a front side frame comprising a side frame portion which has a closed cross-section and is mounted on the side wall of the engine compartment on the front side of a dashboard panel to extend in the longitudinal direction of the vehicle body, and a floor frame portion which has a channel-shaped cross-section with the open portion upward, is connected to the rear end of the side frame portion by way of a junction bent by a predetermined angle in a vertical plane, and is mounted on the lower surface of a floor panel to extend in the longitudinal direction of the vehicle body. A front reinforcement is provided in the side frame portion and a rear reinforcement is provided in the floor frame portion. The front reinforcement and the rear reinforcement are connected together near the bent junction of the side frame portion and the floor frame portion. A gusset is fixed to the junction of the front reinforcement and the rear reinforcement to partition the front side frame in the longitudinal direction thereof.
