Of 119 identified substances, 52 (indicated by 'Std' in column 3 of Table 1) were obtained from Sigma-Aldrich, Belgium. The isotopically labelled internal standards furfural-d4, 2-ethylphenol-d10, m-cresol-d8, and 4-hydroxybenzaldehyde-2,3,5,6-d4 were supplied by CDN Isotopes (Point-Claire, QC), and phenol-2,6-13C2, catechol-13C6, 4-methylcatechol-ring-d3, guaiacol-ring-13C6, and vanillin-ring-13C6 were supplied by Cambridge Isotope Laboratories Inc. (Tewksbury, MA). Methanolic solutions of reference substances spanning the concentration range of 1.0-1.2 mg/L were used for instrument calibration, in order to cover the wide range in detection limits of different smoke flavouring components.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
