7. GC-MS APPLICATIONS
Metabolite profiling
Detection of lipophilic compounds in diverse plant tissues
Analysis of biologically important aromatic amines.
Application to human dosimetry.
For the sensitive and quantitative single-run analysis of acidic
phytohormones. and related compounds, and its application
to Arabidopsis thaliana
Identification of volatile components
For the determination of pyrethroid residues in vegetable
samples
Analysis of Pesticides in Foodstuffs
Environmental and forensic applications
Miscellaneous
8. Metabolite profiling
Toxicity assessment/toxicology
e.g. a specific lesion in liver or kidney
Functional genomics
Nutrigenomics:
e.g. Arabidopsis thaliana leaf extracts
9. Detection of lipophilic compounds
in diverse plant tissues
liphophilic profiling of red and green tomato
10. Analysis of biologically important
aromatic amines and Application
to human dosimetry
e.g. Exposure to 2, 4-difluoroaniline (DFA) was
monitored by GC-MS of DFA adducts bound to
hemoglobin (Hb)
11. For the analysis of acidic phyto
hormones and related compounds
(i) Often, there is a highly local and controlled
production of enzymes of phytohormone bio
synthesis.
Examples; ethylene biosynthetic enzymes in
abscission zones Gibberellins biosynthetic enzymes in
embryo s (seeds) or meristems.
(ii) phytohormone production has unveiled an amazing
degree of interactions
12. Identification of volatile components
and For the determination of
pyrethroid residues in vegetable
samples
volatile components in certified brand of origin (CBO)
Rias Baixas white wines
13. Environmental and forensic
applications
Types of analysis systems :
photo ionization detectors (PIDs) with and without a
GC
electrochemical and catalytic bead gas detection
systems
colorimetric tube systems
ion mobility based systems (IMS)
GC-MS
14. Miscellaneous
Environmental monitoring and cleanup
