Abstract
An optical emission spectrometry instrument may comprise an inductively coupled plasma generator (ICP) with an electromagnetic coil having input and ground connectors. The electromagnetic coil may be mounted to a mounting disk, and the input connector may be coupled to a power output of a radio frequency power source, and the ground connector may be connected to the mounting disk. A spectro-chemical source may be used for sample excitation. The spectro-chemical source and the ICP may have a longitudinal axis. An optical system may be included for viewing the spectro-chemical source with a fixed view axis. The electromagnetic coil may be mounted pivotably around one of its connectors so that the orientation of the ICP can be altered from a first orientation of its longitudinal axis to a second orientation of its longitudinal axis, and vice versa.
