  • Patent number: 11933795
    Abstract: A continuous sample introduction method is provided. The method includes controlling a current sample holder advancing mechanism to perform an advancing operation according to a sample introduction trigger signal, so that the current sample holder advancing mechanism moves in a direction from an initial position to a limiting position, and during the movement, a pushing portion of the current sample holder advancing mechanism is capable of abutting against a side wall of a sample holder in a current sample loading device; controlling the current sample holder advancing mechanism to perform a returning operation when the current sample holder advancing mechanism moves to the limiting position, and during the movement, the pushing portion is capable of avoiding contacting with the sample holder; and the current sample holder advancing mechanism automatically repeats the advancing operation and the returning operation when the current sample holder advancing mechanism moves to the initial position.
