摘要
A flame photometric detector including a burner assembly having a first passageway leading to the burner tip so that a mixture of the hydrogen fuel gas and the combustion supporting gas such as oxygen may be delivered via the passageway to the burner tip to produce a hydrogen rich reducing flame. The sample to be analyzed is delivered via a second passageway and directed by a sample guide to the peripheral region of the reducing flame where the sample is burned in a relatively low temperature, hydrogen rich region. The spectrophotometer is positioned above the flame and having it's optical axis substantially coaxial with the burner assembly for end-on viewing of the combustion chamber.
