Abstract: Provided is a liquid ejection apparatus, liquid ejection method, dispensing apparatus, and compound introduction apparatus capable of inhibiting contamination of a liquid after being ejected. The liquid ejection apparatus has an ejection unit having an ejection part and an ejection energy generation element that ejects a liquid from the ejection part by using a principle of inkjet ejection into an internal space in a storage part capable of storing the ejected liquid. When ejecting the liquid, the ejection unit covers an opening portion of the storage part to thereby screen the internal space in the storage part from an external space.

Abstract: A liquid (ink) supply system having a closed structure with respect to an inkjet recording head is configured such that a gas hindering a recording operation and a liquid supply operation can be rapidly and smoothly eliminated from a liquid supply system without involving any complication in structure. An ink tank (10) and a liquid chamber (50) for leading ink supplied to the recording head (20) are brought into fluid communication via two communication channels (53 and 54). Thus, in the state where the gas exists inside the liquid chamber, the ink is moved from the ink tank (10) via one communication channel (53), while the gas is transferred to the ink tank (10) via the other communication channel (54).
