When solution samples are analyzed spectrographically, gas and liquid vapors are released. Generally, these combustion products are exhausted out of the arc-spark stand by a ventilating system consisting of exhaust blowers, dampers, and ducting. During the exhausting process, liquids and gas vapors condense on parts of the ventilating system. This condensation leads to corrosion of the ventilating system and, eventually, to its replacement. The condensation can also trap toxic and radioactive particles released when solid samples are analyzed.
