Evaluation of GC/MS-Based ¹³C-Positional Approaches for TMS Derivatives of Organic and Amino Acids and Application to Plant ¹³C-Labeled Experiments

Metabolites, 2023
Analysis of plant metabolite 13C-enrichments with gas-chromatography mass spectrometry (GC/MS) has gained interest recently. By combining multiple fragments of a trimethylsilyl (TMS) derivative, 13C-positional enrichments can be calculated. However, this
