TI  - Retention indices as identification tool in pyrolysis-capillary gas 
      chromatography.
PG  - 131-41
AB  - Pyrolysis-capillary gas chromatography (Py-cGC) represents important method to 
      identify the analytes in the mixture after thermal degradation. This combines 
      high effective analyte separation on-line coupled with thermal degradation 
      process that depends on analyte structure. System of retention indices has been 
      used for identification of the analytes after on-line pyrolysis and 
      chromatographic separation. The pyrolysate composition has been studied during 
      thermal degradation of polymethylmethacrylate (PMMA) at different pyrolysis 
      temperatures and chromatographic column conditions. Homologues series of 
      n-alkanes have been used for calculation of pyrolysate Kovats retention indices 
      (I) and compared with mass spectrometric (MS) data of pyrolysate model mixture. 
      To identify PMMA thermal degradation products the high density polyethylene 
      (HDPE) as additive standard producing triplets of the olefin homologous series 
      during co-pyrolysis has been used. These homologous series enable to calculate 
      programmed temperature retention indices (ITPGC) to identify the analytes present 
      in the pyrolysate. Calculated I values were compared with published I values 
      databases to identify analytes yielded at different pyrolysis temperatures.
