HSE: MDHS42/2 Nickel and inorganic compounds of nickel in air (except nickel carbonyl)
Laboratory method using flame atomic absorption spectrometry or electrothermal
atomic absorption spectrometry
Note 1: This method updates and replaces MDHS 42.1
The principal changes which have been made are (i) to describe additional dissolution techniques that are effective for nickel-containing dusts that are difficult to take into solution, (ii) to recommend the use of filters that are soluble using the dissolution techniques described, and (iii) to describe the use of electrothermal atomic absorption spectrometry for the analysis of sample
solutions with a low nickel concentration.
