Reagent splitting/dispensing method based on reagent dispensing nozzle and reagent splitting/dispensing mechanism

摘要

The present invention provides a reagent splitting/dispensing method that can prevent contamination of an operation fluid when a reagent dispensing nozzle (24) is in a waiting state and prevent falling of a droplet. The reagent splitting/dispensing method includes a waiting process (200) of disposing a first air layer between an interface of the operation fluid and a nozzle tip end in the reagent dispensing nozzle (24), a reagent splitting process (240) of filling the reagent into the reagent dispensing nozzle (24), a reagent protecting process (250) of disposing a second air layer in the nozzle tip end, a reagent dispensing process (280) of ejecting the split reagent, an operation fluid protecting process (310) of disposing the first air layer in the nozzle tip end, after dispensing the reagent, and moving processes.
