| Popis: | The effect of a cylindrical impactor in the spray chamber of a flame photometer on the characteristics of the aerosol formed, on the transport-efficiency of the nebulizer-spray chamber system, as well as on the analytical signal has been investigated. The variables were: the diameter Phi of the cylindrical impactor and its position, i.e., the distance d in front of the tip of pneumatic nebulizer capillary where the impactor was fixed. The performance characteristics of an 1 mm Phi impactor was fixed at d=5 mm was superior to that of a conventional 8 mm Phi spherical bead. |
