Characterization of 35 organic pigments using multi-functional pyrolysis (Py)-GC/MS and development of a database
Organic pigments are widely used in paint and ink formulations. The analysis and structure elucidation of organic pigments is challenging because they are not only insoluble in organic solvents but also many of them have similar structures. Py-GC/MS appears to be the most viable analytical technique for the analysis of organic pigments in a complex matrix, like paint. Samples are analyzed directly; no pretreatment such as solvent extraction is necessary. Pyrolyzates are separated on a high resolution capillary column and identified using both spectral(MS) and retention (GC) data. This note describes the Py-GC/MS analysis of relatively large-molecular-weight (MW approx. 1,000) nonvolatile pigments including condensation disazo pigments having similar structures, azo lake pigments, and phthalo-cyanine pigments. The spectral information from the Py-GC/MS analysis is incorporated into a searchable MS library using F-Search. Additional organic pigments can easily be added. Such a “pigment” library can be used to identify pigments in an ‘unknown’ sample.The results obtained by the EGA and Py-GC/MS analysis of Pigment yellow 93 and Pigment yellow 94 are shown below.
Characterization of the Network Structures in UV-Cured Acrylic Ester Resin by Reactive Py-GC
Py-GC is a powerful tool for the characterization of network structures in intractable polymeric materials. Py-GC, in the presence of an organic alkali such as tetramethylammonium hydroxide (TMAH), can be used to analyze the structures of insoluble cross-linking polymers containing polar components. This note describes the characterization of the network structures in an UV-cured acrylic ester resin, prepared from prepolymer compounds containing ester linkages.A UV-cured resin prepared from polyethylene-glycol diacrylate and MA 5 - mer - MA 6 - mer - n = 11 n = 12 ures n = 13 80 MA oligomers morpholino-type photoinitiator (IRGACURE 907) is subjected to Py-GC. First the resin is ground into a fine powder using a freezer mill. About 100 µg of the powder is subjected to reactive Py GC at 400ºC in the presence of 4 µL of 25% TMAH methanol solution.
