Title:
ANALYSIS EQUIPMENT HAVING PLURALITY OF CHROMATOGRAPHS
Document Type and Number:
WIPO Patent Application WO/2019/138725
Kind Code:
A1
Abstract:
The present invention achieves analysis equipment having a plurality of chromatographs, in which the overall operating efficiency can be improved even when analysis items having different analysis times and sample separation times are repeatedly analyzed over a plurality of cycles. A standby period 406 is provided between a dispensing operation 202 for an analysis item B' preceding an analysis item C, and sample introduction 203 into an analysis flow passage, the sample introduction 203 into an analysis flow passage precedes a data collection period 206 for an analysis item A, and the dispensing operation 202 is initiated early on after a sample dispensing operation period 201 for the analysis item A. A sample dispensing operation period 201 for the analysis item C is initiated early on, and an analysis time for the analysis item C can be shifted up to a point immediately following a sample dispensing operation period 201 for the analysis item B'. An analysis item A of a second cycle can be initiated earlier by as much as the early initiation time of the analysis item C of a first cycle. The total processing time Tc according to example 1 can be made shorter than the total processing time Tb in an example not in accordance with the present invention.
