Abstract: A method of evaluating a function of an organ for transplantation harvested from a living body, the method includes preparing data representing change over time in content of marker substances in accordance with a perfusion, taking a first tissue sample from the organ for transplantation at first timing in a reperfusion of the organ for transplantation, taking a second tissue sample from the organ for transplantation at second timing after the first timing in the reperfusion, measuring contents of the marker substances in the first tissue sample, measuring contents of the marker substances in the second tissue sample, calculating change in content at the second timing as compared with the first timing for each of the marker substances, and calculating an indicator relating to evaluation of the function of the organ for transplantation using the calculated change in content and the data.

Abstract: Provided is a gas chromatograph including a column which separates a sample; a detector which is configured to alternately introduce a carrier gas containing a sample component separated by the column and a carrier gas alone into a detection unit by changing an inflow point of the carrier gas to acquire a signal; an analysis information input unit with which analysis information is input; a data retaining unit which retains data indicating a relationship between a column flow rate and a carrier gas flow rate which is obtained in advance; and calculation unit which is configured to calculate the carrier gas flow rate on the basis of the analysis information input from the analysis information input unit and calculate the carrier gas flow rate according to the calculated column flow rate by using the calculated column flow rate and the data retained in the data retaining unit.

Abstract: A thermal conductivity detector that causes a fluid to come into contact with the surface of a heated temperature sensing element, that causes the temperature of the temperature sensing element to change according to the thermal conductivity of the fluid, and that detects the fluid based on a change in the electrical resistance of the temperature sensing element at that time or on a change in the value of a current to be applied to the temperature sensing element is provided. The thermal conductivity detector includes a cell space where the temperature sensing element is accommodated and to which a fluid is introduced and from which the fluid is discharged, a buffer space that is connected to a fluid outlet of the cell space, and a discharge channel that is connected to a fluid outlet of the buffer space.
