Workplace air. Determination of mercury vapour. Method using gold-amalgam collection and analysis by atomic absorption spectrometry or atomic fluorescence spectrometry shop-only Determination of humidification system output1 Scope This International Standard specifies a procedure for determination of the mass concentration of mercury vapour in workplace air using a method of gold amalgam collection with analysis by either cold vapour atomic absorption spectrometry (CVAAS) or cold vapour atomic fluorescence spectrometry (CVAFS). The procedure specifies a number of sampling methods for different applications. a) When it is known that no particulate inorganic mercury
