10. The measured retention times were very reliable and reproducible within a few seconds or sometimes less; thus, they could be used for chemical identification rather well. Nevertheless, a retention time alone is usually not enough to identify an unknown compound with absolute certainty; e.g., as Table 1 shows, retention times for ETA and oxalic acid are the same within experimental error. Therefore some chemical reactions of the unknown compounds, like the decarboxylation reactions applied here, or the spectrophotometric measurements applied by Gao et al. can be very helpful to provide additional information in critical cases. In addition to the hydrolysis and decarboxylation reactions, we used H-NMR for this purpose.
