The system uses a Brewster angle reflector as a passive amplifier. This device reduces intensity without causing a serious reduction in either the signal of interest or the signal-to-noise ratio. It also reduces the need for a high quality analyser.

A field-on-source design is described which gives Zeeman background correction while allowing a significant reduction of magnet size to be achieved. The design is inherently suited to observation of the longitudinal Zeeman effect. The system was test

A radiofrequency plasma is struck between a metal electrode and an aqueous solution. The plasma converts the solution into an aerosol, which can then be transported to an atomisation device such as a flame. The effects of discharge power, sample conc
