Abstract

An outer tube injection-based atomic fluorescence analysis method and an atomic fluorescence analyzer. An outer tube injection-based atomic fluorescence analysis method comprises steps such as sampling and transportation, mixed gas produced by a gas-liquid separator being carried by a carrier gas to enter an atomizer, and atomization and fluorescence detection of an element to be measured, wherein a quartz furnace in the atomizer has a structure in which an inner tube and an outer tube are nested, the mixed gas is introduced into the outer tube of the quartz furnace, and an auxiliary gas is introduced into the inner tube of the quartz furnace. The use of the original quartz furnace to carry out the outer tube injection can facilitate the ignition of hydrogen flame and improve the detection sensitivity.
