摘要： PROBLEM TO BE SOLVED: To cope with problems of liquid chromatograph systems, in which automation is one of the important objects, and the need becomes large that recent users want to operate a system comparatively simply without receiving any special education and training about the liquid chromatography. SOLUTION: Automating processes for purging and bubbling can be realized by respectively controlling a high-pressure switch valve and a solenoid valve by executing a time program; however, if a control according to a fixed time program is always executed, the purging is carried out unnecessarily, or the bubbling is carried out excessively, and an automated system becomes not intelligent. In order to make the system intelligent, it is necessary to devise a process flow which incorporates expert's wisdoms. In the case of purging, it is preferable to carry out the control in accordance with a period of time when a pump is stopped, i.e., a purge period is set short when the stop period is short, and the purge period is set long sufficiently when the stop period is long.

摘要： PROBLEM TO BE SOLVED: To make the advantage of automation and flexibility compatible in a liquid chromatograph apparatus in which the automation is an important problem because of needs of recent users to operate comparatively simply the apparatus even if they receive no special educational training about the liquid chromatography. SOLUTION: The automation of purging and bubbling can be realized by controlling a high-pressure switching valve and an electromagnetic valve with a time program.

摘要： PROBLEM TO BE SOLVED: To provide an automated liquid chromatograph device, which can respond to such needs by recent users that they want to relatively easily operate liquid chromatography devices without participating in special educational training on liquid chromatography.SOLUTION: Automation in purging and bubbling can be achieved by controlling a high pressure change-over valve and an electromagnetic valve, respectively, by a time program. However, when these operations are always controlled by a given time program, an intelligent automated device is no longer obtained because of excessive purging or excessive bubbling. Thereby, it is required to scheme a process flow that takes knowledge of experts for achieving intelligent control. In the case of purging, it is preferable to control purging depending on a time period that a pump is stopped, such that a purging period is decreased with a shorter stop time, and the purging period is increased with a longer stop time.

摘要： PROBLEM TO BE SOLVED: To reduce an analysis cycle time.
SOLUTION: In a liquid chromatograph analysis, the cycle time from current sample injection to next sample injection is fixed. A sample is injected, before a column is equilibrated by an eluting solution. Since the timing, when the eluting solution is switched in each injection/analysis cycle and the timing, when the sample is injected are synchronized, the properties for comparatively and reproducibly solving the hold time of each component peak is applied, even though the column does not necessarily become equilibriated.
