1. A method of detecting an analyte species comprising:
introducing an analyte species into a torch having a longitudinal axis along which a flow of gas is introduced during operation of the torch and having a radial plane substantially perpendicular to the longitudinal axis of the torch;
providing a loop current along the radial plane of the torch using a device configured to generate an inductively coupled plasma in the torch, the device comprising a first plate electrode configured to couple to a power source; and
detecting an optical emission from the analyte species introduced into the plasma generated in the torch.
