Abstract A study on the use of electrothermal vaporization for introduction of solid samples into a direct-current plasma is presented. The solid samples investigated were milligram masses of an alga exposed to various mercury solutions. The results are independent of the algal mass in the 0.6–9 mg range, and give acceptable calibration curves up to 20 mg of mercury absorbed on 5-mg masses of the alga; the relative standard deviation was 7.4% for nine successive samples of 100μg of mercury absorbed by a mass of approximately 3 mg of algal cells. Various mercury compounds gave more than one peak, with different appearance times. Addition of sulphur-containing algal cells or cysteine modified the mercury signal, making it the same (for the compounds tested) irrespective of the mercury compound originally present.
