General protocol information Flux analysis method: 13C constrained MFA

Platform: GC-MS

Methods description - Notes

GC–MS analysis - GC–MS analysis was performed on an Agilent (PaloAlto,CA, USA) HP 6890 gas chromatograph coupled to a HP5973 quadrupole mass selective detector in positive electron impact ionization (EI+) operated at an electron energy of 70 eV. The GC was equipped with a 4. ...
