The liquid chromatograph analysis method comprises the steps of: transferring two or more types of eluents while changing a mixing ratio between the eluents; adjusting an amount of the transferred liquid within a predetermined time in a passage for the eluent transferred; injecting a sample in the passage; supplying to a separation column the eluent into which the sample is injected; separating a target component in the sample; and detecting the target component thus separated. In this method, control is exercised so as to synchronize a liquid transfer cycle of the eluent with the sample injecting operation and to implement the sample injecting operation at a timing rather than the pressure obtaining time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid chromatograph apparatus and liquid chromatograph analysis method","description":"An analysis method is achieved in which pressure variation resulting from sample injection or passage switching by an autosampler does not exert an influence on the control of a liquid transfer pump.
