PROBLEM TO BE SOLVED: To allow efficiently and automatically concentrating a solution in a short time in a gas blowing type concentrating apparatus for concentrating the solution by blowing the gas and vaporizing a solvent. SOLUTION: A nozzle 3a for blowing the gas is attached over an opening of a sample container 1. A spiral flow is generated in the solution by the gas blown from the nozzle and a vaporizing speed of the solution is quickened. A solution level sensor 11 is attached. The blown gas is automatically supplied or stopped by a controlling apparatus based on a signal from the sensor. |
