Abstract
Certain embodiments described herein are directed to jet assemblies that include a substantially inert fluid flow path. In some examples, a jet assembly includes a fluid flow path comprising a substantially inert metal in a fluid flow path. Devices and systems using the jet assembly are also described. In other embodiments, a brazeless or weldless jet assembly is provided. In some embodiments, the brazeless jet assembly may include an inert material or coating, e.g., a silica coating, in a fluid flow path.
Claims21
A jet assembly for use in a flame detector, the jet assembly comprising a flame jet configured to sustain a flame in the flame detector and a fluid flow path in a housing of the jet assembly, in which the fluid flow path is constructed and arranged to be fluidically coupled to a chromatography column at a column end to receive sample from the chromatography column, in which the fluid flow path is constructed and arranged to fluidically couple to the flame jet at a flame jet end, in which the entire fluid flow path from the column end to the flame jet end is formed from a substantially inert metal material, and in which the fluid flow path is present in the housing of the jet assembly without any brazes or welds.
