20:04, 23 March 2019The figures and definitions are outdated. For instance, only in Rock-Eval 2 and coeval instrumentation (from the 80s) CO2 from pyrolysis was still trapped and released for measurement in a TCD(and CO produced was ignored). Since the mid-late 90s, new instruments (SRA, Rock-Eval 6 & 7, HAWK) have infrared cells for "live" detection of both CO and CO2 (e.g., Behar et al., 2001; Carvajal-Ortiz & Gentzis, 2015), so there is no trapping as indicated in Figure 1. Along the same lines, the comment on S3 is wrong.
Now, for the same reasons above, since teh late 1990s, pyrolysis ovens can go typically to 650°C and up to 800°C (in RE6 and &7) and not 550°C, which is only true for older technology).
Check with a fellow Geochemist and correct. Remember that this page is used by non-specialist, I have to constantly correct non-specialist because of inaccurate info like this.
