A process for quantitatively analyzing mercury in incineratable samples which comprises heating a mercury-containing sample in the presence of oxygen to effect complete incineration of the sample and form a vapor containing atomic mercury, passing such vapor through a heated glass tube containing a basic salt, cooling the vapor, bringing the cooled vapor into contact with a metal capable of amalgamation to capture the mercury as an amalgam, heating the amalgam to regenerate mercury vapor and measuring the quantity of that vapor. According to this invention, the quantitative analysis of mercury can be attained rapidly and automatically in a simple and precise manner without application of a particular preliminary treatment. |
