An inexpensive tantalum boat vaporisation device has been coupled directly to a microwave-induced plasma for the determination of iodine in hydrochloric acid. The vaporisation device was fabricated from polytetrafluoroethylene and powered by a Shandon Southern A3370 electrothermal atomiser. Detection limits of 2 × 10–10 g at 206.163 nm and 1 × 10–9 g at 506.120 nm were obtained for aqueous solutions.
