1. An analysis assistance device that assists 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, comprising:
a storage that stores 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;
a receiver that receives one of a value of the sample introduction ratio and a value of the differential pressure;
a first calculator that calculates the sample introduction ratio or the differential pressure, whichever is not received by the receiver, from the one value received by the receiver based on the first relationship; and
a presenter that presents the calculated value.
