Analysis assistance device, analysis assistance method, non-transitory computer readable medium storing analysis assistance program and analysis system

An analysis assistance method of assisting determination of an analysis condition of a supercritical fluid chromatograph including a liquid sender that supplies a mobile phase including a supercritical fluid to a supply flow path, first and second back pressure regulators that are respectively provided in first and second flow paths into which the supply flow path branches and an analysis column provided at a position farther upstream than the first back pressure regulator in the first flow path, including:

• storing a relationship between a sample introduction ratio representing a ratio of an amount of a sample to be introduced into the first flow path with respect to an amount of a sample to be introduced into the second flow path, and a differential pressure between the first and second back pressure regulators as a first relationship;
• receiving one of a value of the sample introduction ratio and a value of the differential pressure;
• calculating another value between the sample introduction ratio and the differential pressure from the one received value based on the first relationship;
• and
• presenting the calculated value.
