A system and method for evaporating a sample, and a delivery needle (70) assembly for the system. The delivery needle (70) is provided with a first channel (71) and a second channel (72); the second channel (72) is located on the outer side of the first channel (71); a plurality of holes (77) are formed on the outer wall of the delivery needle (70) on which the second channel (72) is formed; a sample can enter a container (90) through the first channel (71); the second channel (72) of the delivery needle (70) can provide a solvent and a gas, so that a solvent located in the second channel (72) is applied to the inner wall of the container (90) by means of the holes (77); in addition, in the process of heating the container to evaporate the sample in the container (90), gas is provided for the container (90) through the first channel (71). According to the system and method for evaporating a sample, sample injection can be automatically performed, evaporation is accelerated, and residual samples on a container
