GC-TOF/MS analysis An aliquot of 1 μL of each derivatized sample was injected in a splitless mode by autosampler Combi-PAL Agilent (Waldbronn, Germany) into an Agilent 7890 gas chromatograph coupled to a Pegasus II time-of-flight (TOF) mass spectrometer (Leco Corp., St. Joseph, MI, US...

The MS must remain upright at all times; this requires special caution when moving. The MS should not be left vented to atmosphere for long periods. For more information, see "To Move or Store the MS" in the Agilent 7200 Q-TOF GC/MS Troubleshooting and Maintenance Manual. 7200 Accurate-...
GC-MS I.1Gas Chromatography Mass Spectrometry J.Kopka1 1Introduction GC-MS technology has been used for decades in studies which aim at the exact quantification of metabolite pool size and metaboliteflux.Exact quan-tification has traditionally been focused on a single or small set of pre...
Gas chromatography coupled with mass spectrometry (GC-MS) is one of the technologies widely used for qualitative and quantitative analysis of small molecules. In particular, GC coupled to single quadrupole MS can be utilized for targeted analysis by sele
The acquired MS data from GC-MS were analyzed using the Chroma TOF software (v 4.34, LECO, St Joseph, MI). Metabolites were analyzed qualitatively using the NIST and Fiehn databases, which were linked to the Chroma TOF software. Briefly, after alignment with the Statistic Compare component, ...
Gas chromatography–mass spectrometry (GC–MS) with cold electron ionization (EI) is based on interfacing the GC and MS instruments with supersonic molecular beams (SMB) along with electron ionization of vibrationally cold sample compounds in SMB in a fl
