    摘要: The present invention aims to shorten an aspiration time, when aspirating a red blood cell component of a liquid sample having high viscosity. When aspirating the red blood cell component of a blood sample through a nozzle tip, a piston is pulled at its maximum to produce a maximum aspirating force, and starts aspiration. When a pressure in an aspirating system becomes equal to a predetermined value .alpha., the piston is returned to a position in which only a necessary aspiration volume of the liquid sample can be aspirated. Since the maximum aspirating force of the pump is utilized during the aspiration, the aspirating operation can be carried out more quickly.

    摘要: In a Fourier transform nuclear magnetic resonance spectrometer, as is known, a pulse modulated radio frequency is applied to a sample placed in a magnetic field, and a free induction decay signal resulting from the above application is Fourier transformed to obtain a nuclear magnetic resonance spectrum. In such a spectrometer, a material having a predetermined resonance peak, for example, tetramethylsilane is used as a reference sample, and the center frequency of the pulse modulated radio frequency is successively varied while maintaining a constant magnetic field intensity. The position of peak of tetramethylsilane in frequency spectra thus obtained is varied with the change of the center frequency. By measuring successively the signal strength of the peak, there can be obtained a frequency characteristic of a receiving system employed in the spectrometer, which is used to obtain correction coefficients of the receiving system. By multiplying a frequency spectrum of a sample to be analyzed by the correction coefficients, the frequency characteristic of the receiving system is corrected, and thus the signal strength of the frequency spectrum can be indicated with high accuracy.

    摘要: A pipetting apparatus is provided with clot detection. The pipetting apparatus comprises a nozzle for aspirating a sample. A pressure sensor is connected with the nozzle for measuring pressure in said nozzle. A plurality of pressure difference calculating circuits are operatively connected with the pressure sensor, each for inputting an output of said pressure sensor and obtaining a pressure difference at a different pressure calculation period, respectively. A plurality of discriminating circuits each having a different discrimination threshold value determined according to each of the pressure calculation periods are provided. An alarm circuit is included for outputting a clot detection alarm signal when at least one of said discriminating circuits discriminates that the obtained pressure difference exceeds the discrimination threshold value.
