Several solid organic compounds containing bromine and chlorine were analyzed with laser-induced plasma spectroscopy. Emission lines were detected in the near vacuum ultraviolet spectral region by using a gas-purged spectrograph and an intensified charge-coupled device detector. The performance of this setup in the determination of the halides in the organic samples was evaluated. Carbon emission lines in the near vacuum ultraviolet were used as internal standards for the measurement of chlorine and bromine. Linear correlation was found between the carbon and halogen emission signal ratio and the corresponding atomic ratio of the compound.
