Figure 12.10 Microcolumn SEC-LC analysis of an acrylonitrile-butadiene-styrene (ABS) teipolymer sample (a) SEC ti ace (b) EC ti ace. SEC conditions fused-silica column (30 cm X 250 mm i.d.) packed with PL-GEL (50 A pore size, 5 mm particle diameter) eluent, THE at a flow rate of 2.0 mL/min injection size, 200 nL UV detection at 254 nm x represents the polymer additive fraction (6 p-L) tr ansferred to EC system. EC conditions NovaPak CIS Column (15 cm X 4.6 mm i.d.) eluent, acetonitrile-water (60 40) to (95 5) in 15 min gradient flow rate of 1.5 mL/min detection at 214 nm. Peaks identification is follows 1, styrene-acrylonitrile 2, styrene 3, benzylbutyl phthalate 4, nonylphenol isomers 5, Vanox 2246 6, Topanol 7, unknown 8, Tinuvin 328 9, Irganox 1076 10, unknown.

Cortes et al. [634] have recently used /rSEC-GC/LC in a comparative quantitative study of dissolution and dissolution/precipitation of PC/(2,4-di-f-butylphenol, nonylphenol isomers, Tinuvin 329, Irgafos 168) and ABS/(nonylphenol isomers, Tinuvin P, BBP, Vanox 2246, Tinuvin 328/770, Topanol CA, Acrawax). For the ABS sample the dissolution approach determined a four-fold higher concentration for Vanox 2246 than by dissolution/precipitation of the sample, indicating that precipitation can yield low (incorrect) results for additives which exhibit solubility dependence. Using both sample preparations equivalent concentrations were observed for the additives of the PC sample, except for Tinuvin 329. 

Specimens were post-fixed in 1% OSO4 in sodium cacodylate buffer, dehydrated in ascending alcohol solutions, and embedded in Epon LX 112. Semi-thin sections (1.0 pm thickness) were cut with a diamond knife and stained with Richardson s dye (contains methylene blue) or PAS-reagent. Micrographs were made with an Olympus New Vanox microscope. 

The green hairy roots cultured in the light for 3 weeks were used for the fluorescent microscopy and transmission electron microscopy (TEM). For the fluorescent microscopy, frozen sections (15 pm in thickness) were prepared using microtome cryostat (HM 500 OM, Microme, Heidelberg, Germany) and sealed with 50% glycerol on glass slides. Localization of chloroplasts was observed by fluorescent microscopy (VANOX AH-3, Olympus). 

Figure 5. CL monitored degradation ofPP(l 10°C) and inhibited by volatile antioxidant transferred from the left sample stage (50pg Vanox MBPC).
