Abstract
The invention discloses an atomic fluorescence analysis method and device using water as a carrier fluid, belonging to the atomic fluorescence analysis in the field of analytical chemistry; the method is to replace hydrochloric acid and a reducing agent with water as the carrier fluid in the conventional sampling and fluid delivery process to carry the test liquid and reagent into the reactor to complete a reaction. The invention effectively overcomes the memory effect by using water as the carrier fluid and improves the determination sensitivity and accuracy, which saves a large amount of high-purity hydrochloric acid and reducing agent at the same time, greatly reducing the analysis cost, and significantly improving the operating environment, which is the innovation of atomic fluorescence analysis technology.
