摘要： The present invention provides a liquid delivery device for liquid chromatographs which, by performing liquid delivery at an accurate flow rate with limited pulsation, gives accurate results of analysis. The present invention, with a view to preventing erroneous operation due to errors in measurements at the time of judgment of completion of compression of liquid, establishes the judgment point before the pressure measured by a cylinder pressure detector agrees with the pressure measured by a discharge pressure detector and also calculates the point of completion of compression. Control in this manner prevents pressure fluctuation. It also calculates for control the point of completion of compression from the history of compression performed previously.

摘要： An object of the present invention is to improve the accuracy in analysis repeatability of a liquid chromatography apparatus that feeds different eluent by use of a plurality of pumps and achieves the mixture of eluent.Each of the pumps includes means for notifying an automatic sampler and a higher-level control unit that the specified timing of a liquid feeding cycle is reached. A pump whose liquid feeding cycle is the slowest transmits own information so that analysis is synchronized with a liquid feeding cycle. Moreover, a cycle position of a liquid feeding cycle at the end of analysis is expected, and the analysis time is automatically adjusted so that the wait time until the start of the next analysis becomes the shortest.

摘要： Provided is a liquid chromatograph system and method configured to accurately obtain measurements by minimizing deviations in measurements due to a transfer from one measurement method to another measurement method. An aspect of the system and method includes minimizing deviations in measurements when a measurement method from a measurement system of a liquid chromatograph is transferred to measurement system under high pressure and high velocity. Such a transfer includes deviations due to differences in analysis conditions. The present subject matter uses a dwell volume value so as to minimize a deviation of measurement result due to methods before and after transfer.
