Patent ID: 8578789

Claim:
An analysis method using an analysis apparatus comprising a resistive body, a supply piping that is provided at an upstream side of the resistive body and supplies a liquid to the resistive body, a pressurizing pump that is provided at a halfway of the supply piping, a discharging piping that is connected to the resistive body and discharges the liquid supplied to the resistive body, a flow rate sensor that is arranged at a halfway of the discharging piping of the resistive body, a pressure-reduction pump that is provided at a downstream side of the resistive body and through the discharging piping, and a pressure-reduction bottle that is arranged between the flow rate sensor and the pressure-reduction pump and is connected to the pressure-reduction pump, the analysis method comprising: a first step of driving the pressurizing pump and the pressure-reduction pump, of reducing a pressure in the pressure-reduction bottle, and of filling the liquid from the supply piping in an interior of the resistive body through which a sample passes; a second step of discharging, from the discharging piping, some of the liquid filled in the interior of the resistive body, and of securing a space in the interior of the resistive body for filling the sample; a third step of supplying the sample into the space; a fourth step of causing the sample to travel in the interior of the resistive body; and a fifth step of measuring a travel time of the sample in the interior of the resistive body by using the flow rate sensor.
