Transposition of directives containing indicative values for 122 chemicals required inclusion since 2002 to the Polish list of MAC (TWA) 3 new chemicals (2-(2-butoxyethoxyethanol, neopentane, bisphenol A), and reducing the occupational exposure limits for 41 chemicals.
The products were swept out of the reactor and mixed with a reference gas used as an internal standard in GC analysis (20 mLmin-1, 0.507 vol.% neopentane in nitrogen) before passing to the special sampling system.
