* REFRI = literature retention index, obtained from the NIST11 database. The column type selected in NIST11 database for RI values is a DB-5 column (30 m \(\times\) 0.25 mm \(\times\) 0.25 \(\upmu\)m). If not available, the RI values of HP-5 column (30 m \(\times\) 0.25 mm \(\times\) 0.25 \(\upmu\)m) was chosen. 2 Identification Methods = Std (authentic standard retention time); MS (Mass spectrum) with minimum match of 70%; RI (Retention Index). 3 Ion = quantification region response.
