The orientation of the tips is fixed by the manufacturer and may include a sapphire edge at the tip of the solution tube to produce a fine, uniform mist out of approximately 10% of the solution drawn in. The concentric-flow (Meinhard-type)glass nebulizers are routinely used at the DANR Analytical Lab for both ICP-AES and ICP-MS work. These are made entirely of glass in a T-type configuration. The main barrel of the nebulizer consists of a fine glass tube tapered to capillary size. The capillary portion carries the sample solution, is approximately 1 in.

Polystachyon, and t! macrourum have been reported to be apomictic (Dujardin and Hanna, 1984). Apomixis may have played a role in building and maintaining new genome combinations in Pennisetum. Hanna and Dujardin (1991) summarized some of their research, which showed how apomixis was used in crosses among two sexual and three apomictic species in the x = 7 and x = 9 chromosome groups from the primary, secondary, and tertiary gene pools to develop and maintain more than 20 new chromosome and/or genome combinations.
