Analytical method for the determination of lead and its inorganic compounds
Translation of DGUV Information 213-573 (former BGI 505-73)
CAS Number: 7439-92-1
Method 01 – GFAAS
Sampling is carried out with a pump and collection on a membrane filter. Analysis is performed by graphite furnace atomic absorption spectrometry (GFAAS) after acid digestion.
This method can be used with personal or stationary sampling to determine the mean concentration of lead and its inorganic compounds at workplaces over the sampling time.
Principle
A pump draws a defined volume of air through a membrane filter. The lead contained in the collected aerosol is determined by means of graphite furnace atomic absorption spectrometry after acid digestion.
Limit of quantification (LOQ)
Absolute: 0.044 ng of lead.
Relative: 0.13 µg/m3 for an air sample of 1.2 m3, a sample solution of 20 mL (dilution factor 4) and an injection volume of 20 µL.
