    摘要: A reference sample having a known concentration is injected into a chromatograph system before an unknown sample is analyzed. This is for the purpose of checking the deterioration of system performance or in other words for the purpose of checking system suitability. In the present invention, the chromatographic characteristic of the check sample at the time of deterioration of the system suitability is expected and stored in a memory in advance to be related to factors of deterioration of system suitability. A factor of deterioration is deduced by comparison between the actually analyzed chromatographic characteristic of the check sample and the relational data stored in the memory. A guidance required for removing the factor is displayed. Disclosed are preferred embodiments of a chromatograph system suitable for analyzing catecholamine or glycated hemoglobin.

    摘要: A method for analyzing amino acids in biological liquids wherein a buffer liquid including unknown components to be analyzed is introduced to a separation column for separating amino acids. After reaction of the buffer liquid in a reactor, the amino acids are detected by a photometer. The flow rate of the buffer liquid is maintained at a predetermined value until the asparagine, glutamine acid and glutamine are separated from the separation column and the flow rate of the buffer liquid is varied stepwise or in linear gradient after separation of the above three components from the separation column.

    摘要: In a fiber optic rate sensor employing a Sagnac ring circuit wherein an ocal source launches an optical signal which is divided into two equals signals which are coupled in opposite directions through a multi-turn fiber optic coil to provide two counter-propagating optical signals. The two counter-propagating optical signals are coupled to a photodetector after passing through the multiturn fiber coil. The signals detected at the photodetector have traversed identical optical paths between said source and said photodetector and have undergone a Sagnac phase shift directly related to the rate of rotation of the fiber coil about its axis in inertial space. The two counterpropagating signals are phase modulated by a phase modulator at one end of the fiber optic coil and the output of the photodetector undergoes signal processing in a signal processor to produce a rate output directly related to the rate of rotation of the fiber coil. The improvement being an improved phase modulation and signal processor which comprises a crystal-controlled oscillator providing a sine wave reference signal means for coupling the crystal of the crystal-controlled oscillator to the optical fiber at one end of the coil to produce a non-reciprocal phase modulation of the counter-propagating optical signals, means for multiplying the sine wave reference signal and the output from the photodetector to produce a product output, and means for integrating the product output over a whole number of complete reference cycles to produce the rate output, the sine wave reference signal being coupled to means for integrating to control the integration period of the means for integrating.
