摘要： A method and an instrument for separating and analyzing a very small quantity of constituents to be inspected contained in an analyte such as a class of catecholamines by liquid chromatography after labeling. The entire processes of analytical operations include principally three processes, a preparing process, an impurity elimination process and a separation process. When one sample is perceived, the sample is processed in these three processes. In this case, while one sample is being processed in an impurity elimination process, a sample preceeding the one sample is processed in a separation process, and a succeeding sample is processed in a preparing process. In other words, these three processes are performed essentially in parallel. With this, it is possible to remarkably reduce analysis time as compared with individual single sample analysis.

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 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.
