Analysis assistance device, method, and program for searching for an analysis condition for use with a liquid chromatography system

An analysis assistance method performed by a processor for searching for an optimal analysis condition for use with a liquid chromatography system, the method comprising:

• receiving by the processor a plurality of analysis conditions, wherein each of the plurality of analysis conditions includes values for a plurality of analysis parameters;
• obtaining by the processor a measurement data set comprising measurement data from the liquid chromatography system for each of the plurality of analysis conditions;
• calculating with the processor a measurement quality data set comprising measurement quality data for each of the measurement data of the obtained measurement data set;
• estimating with the processor as distribution data a distribution of the calculated measurement quality data set relative to the plurality of analysis parameters;
• and
• display as a design space a region of the distribution data where the measurement quality index data is greater than or equal to a predetermined threshold value, wherein:
• the design space includes a plurality of boundaries and the plurality of analysis parameters as axes, and
• the design space is displayed such that when the design space includes a change in the measurement quality data that is larger than a change in the plurality of analysis parameters:
• the region is enlarged as an enlargement region;
• and
• the enlargement region is based on a spacing between each of boundaries, such that a small spacing between each of the boundaries compared to each spacing of an other area along a direction of an axis of the design space results in a large spacing in the enlargement region by cutting off at least part of the enlarged area in the design space of the measurement quality index data.

A non-transitory computer readable storage medium recording an analysis assistance program for searching for an optimal analysis condition for use with a liquid chromatography system that when executed by a processor causes the processor to:

• receive a plurality of analysis conditions, wherein each of the plurality of analysis conditions includes values for a plurality of analysis parameters;
• obtain a measurement data set comprising measurement data from the liquid chromatography system for each of the plurality of analysis conditions;
• calculate a measurement quality data set comprising measurement quality data for each of the measurement data of the obtained measurement data set;
• estimate as distribution data a distribution of the calculated measurement quality data set relative to the plurality of analysis parameters;
• and
• display as a design space a region of the distribution data where the measurement quality data is greater than or equal to a predetermined threshold value, wherein:
