APPARATUS FOR ANALYSING REDUCED INORGANIC SULFUR

摘要

An apparatus for measuring the reduced inorganic sulfur content of a sample. The apparatus has a reaction chamber (12) and means (14) for introducing a reducing agent that can selectively convert the reduced inorganic sulfur of a sample in the reaction chamber (12) to hydrogen sulfide. The reducing agent can be chromous chloride. The apparatus also includes means for measuring th e amount of hydrogen sulfide evolved by reaction of the reducing agent with th e sample and a detector for detecting when evolution of the hydrogen sulfide h as reduced or ceased. The term "reduced inorganic sulfur" refers to sulfur in a form that can undergo oxidation and includes mineral sulphides and elemental sulfur.
