  • Patent number: 10401334
    Abstract: The present invention aims at reducing the time required for a series of analyses in the sequential performance of gradient analyses under a variety of conditions. To this end, in a control apparatus for controlling the operation of a liquid chromatograph having a gradient analysis function in which a mobile phase composed of a plurality of mixed solvents is used and a chromatograph analysis is performed while the mixture ratio of the solvents is temporally changed, the liquid chromatograph is controlled so as to continuously change the mixture ratio of the solvents from an initial mixture ratio to a final mixture ratio when performing a sample analysis; and as to perform, before the sample analysis, a preparatory liquid supply in which the mixture ratio of the solvents is continuously changed from the initial mixture ratio to the final mixture ratio at a rate higher than that in the sample analysis.

  • Patent number: 9546987
    Abstract: A liquid chromatograph control system for controlling an operation of a liquid chromatograph which uses a mobile phase composed of a mixture of solvents and which has the function of performing a gradient analysis while temporally changing the mixture ratio of the solvents. The system initially requests a user to set a basic gradient profile (Step S12), and subsequently, to set the number of steps to change the mixture ratio of the mobile phase at the beginning and/or at the end of the gradient process as well as the amount of change in the mixture ratio per step (Step S13). After that, based on the possible combinations of the mixture ratios of the mobile phase at the beginning and at the end of the gradient process computed from the contents of information entered in the previous steps, a plurality of gradient profiles corresponding to those combinations are created (Step S14).

  • Patent number: 8007968
    Abstract: In the present invention, patterning for the first time is performed on a film to be worked above the front surface of a substrate, and the actual dimension of the pattern formed by the patterning for the first time is measured. Based on the dimension measurement result of the patterning or the first time, the condition of patterning for the second time is then set. In this event, the condition of the patterning for the second time is set so that a difference between the dimension of the patterning for the first time and its target dimension is equal to a difference between the dimension of the patterning for the second time and its target dimension. Thereafter, the patterning for the second time is performed under the set patterning condition.
