ABSTRACT:
A burner for a flame photometric detector includes a stainless steel housing having a passage therethrough; a stainless steel burner tube extending through the passage and having a flame holder at one end; and at least one stainless steel inlet tube extending through the housing for admitting a support gas to the burner. The burner tube and inlet tube are brazed to the housing to form a unitary device having no sealing rings which can degrade and leak. A transfer line is connected to one end of the burner to conduct the material to be tested to the burner. The transfer line includes a fused silica tube surrounded by a stainless steel outer tube.
