Cold Vapor Spectroscopy (CVS) is used to determine concentrations of heavy metals that are highly toxic, usually mercury. The problem with a Cold Vapor Spectrometer is that they can be very costly so instead of purchasing a new instrument an existing spectrometer can be altered. In this case, I used a Varian 240 Flame Atomic Absorption Spectrometer (AA) and made minor adjustments to the instrument and setup an apparatus for this type of analysis.
