GC-MS Comparison of Lavindin Grosso Oil Obtained by Steam Distillation and SFE
Oil was extracted from Lavindin Grosso using steam distillation and using supercritical fluid extraction (SFE). Multiple analyses of the same extract demonstrated repeatability of the analytical method. The variability between batches of distillate bracketed the composition obtained by SFE. The differences among the oils could be attributed more to where the lavender was grown than to the extraction method.

Isolation, Identification, and Determination of Designer Anabolic Steroids Commonly Found in Dietary Supplements
A general analytical approach in identifying emerging steroid-like compounds is presented, including analysis by GC-MS, LC-MS, and/or HPLC-UV. Isolation of unknown compounds was achieved by high performance liquid chromatography with fraction collection. Isolated compounds were characterized by Nuclear Magnetic Resonance spectroscopy and high resolution accurate mass-mass spectrometry to elucidate their structure.

Identification and classification of antifouling compounds secreted by anti MIC microorganisms. A metabolomic analysis.
BIOCORIN project, aims to develop a green alternative to the coatings and solutions used up to date for MIC corrosion control. Some of the results of this project are presented here, with the identification of several relevant antifouling compounds secreted by environmentally isolated anti-MIC strains of microorganisms via a metabolomic approach.
