4.3.4 Set-up for Heart-Cut EGA Analysis and operation procedure
Heart-cut EGA analysis requires a Selective Sampler. If low boiling components below C
15
are to be
analyzed, a cryo trap is required. Frontier Labs MicroJet Cryo-Trap is recommended.
Heart-Cut EGA analysis is based on evolved gas curve (EGA thermogram) obtained by Direct EGA
Analysis. The temperature zone (elution time range) to be analyzed is based upon the EGA
thermogram. Each EGA thermal zone is automatically introduced into the GC column utilizing a
Selective Sampler. For example, six EGA thermal zones are observed in the EGA thermogram (100
to 600°C (20°C/min) of a ceramic composite material – see Fig. 4.17.
