GC-MS Analysis of HWE-Extracted Fractions

Pyrolab2000
(Pyrolab, Sweden) analytical-scale equipment directly connected to
Bruker Scion SQ456-GC/MS equipped with an Agilent DB-5MS UI (5%-phenyl)-methylpolysiloxane,
30 m × 0.250 mm × 0.25 μm l m) capillary column was
used for analysis. HWE-extracted fractions (A) were analyzed, and
carbohydrate versus aromatic fragment ratios were estimated according
to Kuuskeri et al.^{49 (link)} Details of the analysis
method are given in S1.7.

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.
