High Resolution GC-TOFMS and GC×GC-TOFMS are useful for a non-target comprehensive characterization of petroleum through a petroleomic approach, and can also provide targeted analysis of chemical markers.

High Resolution GC-TOFMS analysis with high resolution and high mass accuracy is crucial for identification of crude oil and asphaltene pyrolysis products by unequivocal chemical formula assignment, with enhancement of sensitivity and selectivity.

Purpose: Exploring the possibility to perform a quantitative determination of dissolved gases in water in a reliable and accurate way. Methods: The quantification of dissolved gases is performed by building a calibration curve spiking blank water samples with increasing quantities of saturated water followed by headspace sampling and GC/ FID analysis. Results: The results show good correlation factors and limit of quantification lower than 10ppb for the four gas analyzed.

GC-HRT is an indispensable tool for complex sample analysis.
-Accurate mass measurements can be leveraged to calculate robust chemical formulae
-A workflow that includes complementary EI and CI-HRT analysis results for rigorous compound indentification

These results show the utility of high resolution time-of-flight mass spectrometry with high mass accuracy for comprehensive petroleomic studies. GC-HRT MS is especially useful for adding structural information in the analysis of complex samples like crude oil.

Py-GC-HRTOFMS analysis with high resolution and high mass accuracy is crucial for identification of crude oil and asphaltene pyrolysis products by unequivocal chemical formula assignment, with enhancement of sensitivity and selectivity. Analysis of petroleum and respective asphaltene fractions from diverse geographical origins are under evaluation as part of future work.

The Pacific Environmental Science Centre (PESC) had been using a LIMS developed in the 1970s but, with multi-functionality required, covering 105 applications, and with 12 functional areas of the laboratory and around 500,000 tests conducted per year, the system was becoming increasingly more difficult and time-consuming to maintain.

Agilent Technologies DP technology is the detector of choice for sulfur analysis when dealing with a hydrocarbon matrix.

Although use of Sudan dyes in food is restricted, they are nevertheless sometimes added to foods to improve the appearance and command a higher price. Because Sudan dyes may create health problems such as genotoxic and carcinogenic effects, concerns over contamination of Sudan dyes has increased awareness and testing for these compounds.

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.

Wax content is an important characteristic affecting the physical properties of petroleum crude oils, in particular their viscosity. Thus, measuring wax content has become a routine analytical requirement for product quality control. The precise monitoring of the wax content in oils helps to predict and avoid wax blockage so that equipment can be maintained for high quality standards during oil processing.
