Apply a factor of 0.4697 to the weight of PHVA to convert it to that of phthalic anhydride. For example, 10 mg of PHVA dissolved in 10 mL will give a standard stock solution representing 0.4697 mg/mL or 469.7 µg/mL of phthalic anhydride. (MW phthalic anhydride)/ (MW PHVA) = 148.12/315.33 = 0.4697. 3.3.2.

An apparent general limitation of coated vials is that they might be difficult to apply for in situ sampling. The multiple coating approach has some important general features ( Reichenberg et al., 2008 ), and allows, for instance, equilibrium sampling to be confirmed without tedious time series measurements ( Bartkow et al., 2004 ; Mayer et al., 2003 ).
