Method and apparatus for preprocessing sample according to form by hydride introduction method

Abstract

A sample preprocessing method converts a substance to be measured in a sample solution into a volatile hydride and introduces the substance into an analytical device. The method includes the following steps (A) to (D) to be performed inside a reaction apparatus connected as a series of processes: (A) a step in which a sample solution is measured and is introduced into a reaction tank of the reaction apparatus; (B) a hydrogenation step in which the sample solution and a reagent are reacted in the reaction tank to produce a hydride; (C) a collection step in which the hydride is guided to a cooling trap to be collected; and (D) a separation step according to a form, in which a temperature of the cooling trap is increased to successively separate a hydride with a low boiling point from the hydrides and guiding to the analytical device.
