ABSTRACT:
The present invention is directed to a nebulizer for use in an atomic absorption system which includes a capillary assembly having a capillary holder having an internal axial passage therethrough, a sapphire capillary tip mounted on one end of the capillary holder and the other end of the holder being connected to a sample liquid source through a capillary gland nut assembly. A venturi member is provided which has an inlet portion, a throat portion and an exiting bell shaped portion. A body assembly has one end connected to the venturi member. The capillary assembly is mounted on the body assembly for axial movement so that the capillary holder partially enters the venturi inlet portion and the capillary tip enters the venturi throat. Compressed oxidant is supplied to the venturi member in the vicinity of the capillary tip so as to suck sample liquid from the capillary tip to form a mixture of fine liquid mist and gas which is discharged through the exiting bell shaped portion.
