GC-MS – Multimedia

This application demonstrates the extraordinary flexibility of the GX-271 ASPEC and TRILUTION LH software since the desired SPE products can be eluted in fractionated mode.

A workflow has been described enabling the automated selection of the most suitable extraction conditions (type of fiber, extraction time and temperature) for the GC/MS analysis of a number of contaminants in oil and water samples.
Applying the automated workflow described above the total time to identify the most suitable fiber and then optimize conditions was 4.5 days. Compared to performing the experiments manually which is estimated at 15 days this represents of time saving of 10 days.

Dispersants are plasticizers commonly used to prevent clumping and help dissipate oil slicks. In this work, we used GC/MS and LC-MS/ MS to detect and indentify two of the most widely used dispersants (Corexit 9527 and 9500).

In order to help understand the impact that the oil spill has caused, laboratories are looking for rapid and robust analytical procedures to characterize the hydrocarbon contaminants. This work provides SPE, GPC, GC-FID, GC/MS, and HPLC analytical methods for analyzing the most common contaminants that originated from the leak.

There is an increasing concern about the different response and effect that acute exercise induces on diabetic people and a novel insight into this effect can be performed using a metabolomic approach. Metabolomic is becoming widely spread used as a new and powerful tool for discerning significant changes at metabolic level. In this study we aimed to perform a non-targeted analysis and to identify metabolic differences arisen after 30 minutes of acute exercise in both young men suffering from Ty

EPA Method 524.2, “Measurement of Purgeable Organic Compounds in Water by Capillary Column Gas Chromatography/Mass Spectrometry”, is a general-purpose method for the identification and simultaneous measurement of purgeable volatile organic compounds in surface water, groundwater, and drinking water.

This poster dealt with the impacts of climate on water-use and water-use efficiency of woodlands in the Sudanese Sahel region. Results are based on global circulation models (GCMs).

The resistance in potato cultivars against late blight caused by Phytophthora infestans is classified into vertical and horizontal. Several metabolites associated with resistance have been detected: phytoalexins such as rishitin, phytuberin, lubimin, solavetivone etc. Metabolite profiling is a novel technology for the discrimination of quantitative resistance in plants against pathogen stress.

To evaluate the efficacy of the traditionally used herbal remedy Radal a metabolite profile of the original plant material was established. The EtOAc extract of the leaves and found to be active against the pathogenic fungus Candida albicans (MIC = 8 µg/ml). Cinnamic acid (2) and vanillic acid (5) were identified as the major constituents in the tea by GC-MS along with other phenolic derivatives.
