BTEX compounds (benzene, toluene, ethylbenzene and xylene) are a group of Volatile Organic Compound (VOCs) that are responsible for various environmental and human health problems. The key sources of VOCs are industrial processes (especially those involving solvents) vehicle emissions, leakage in underground storage tanks, pipeline leaks, surface spills, refinery facility leaks, vehicle and aircraft emissions, paints and adhesive Accurate and reliable BTEX testing is crucial not only in pr...

Structural elucidation of hydrocarbon classes, heteronates impurities and functional biomarkers in petroleum products are always in high demand. Sheer number of compounds in petrochemicals sample quickly exceeds the available peak capacity of single-column GC techniques. Consequently the use of multidimensional separation techniques is almost invariably required. Despite the superior separation afforded by GCxGC, the identification of individual compounds in complex petrochemicals remains cha...

Per- and polyfluoroalkyl substances (PFASs) is a group that compromises more than 3000 different substances that are extensively used in a broad range of applications and products. Many PFASs are extremely persistent in the environment and the human body and can accumulate over time. As a consequence it is estimated that a large number of water utilities in the US are contaminated by PFASs. The aim of this presentation is to provide an overview of the methodology and challenges regarding anal...

An analytical testing laboratory in Spokane, Washington was poised for growth in a relatively new industry. However, the team quickly recognized that, with continued growth, they would need to look for ways to enhance the efficiency of their workflow.  To address known, and perhaps unknown, issues, the team decided to consult with Agilent. Agilent, the maker of the lab’s analytical instruments, is known for assembling complete workflows and for its expertise in lab management, gained o...

This eLearning session is for anyone analyzing residual solvents or interested in quantitative GC-Headspace analyses.         GC-Headspace is a powerful technique for the analysis of volatile compounds in neat samples or in a variety of matrices. A major use of GC-Headspace is the analysis of pharmaceutical drugs, as well as intermediates and excipients for the presence of residual solvents that may be left over from the manufacturing process. The sample that is analyzed by this t...

A Recently developed, free to use, web-based computer program has been employed to accelerate Gas Chromatography (GC) method development by direct simulation of the chromatographic process. The program makes use of a highly accurate time-summation modeling approach, coupled with large libraries of data to provide absolute retention time predictions within 1% of those obtained from experiment.  The user is able to directly control every parameter of the chromatography being modeled includi...

Owing to the high complexity of the matrices to be investigated, petroleum industry has to face a tough analytical challenge when a detailed characterization is required or not. It can be the case for different reasons such as to reach for the specifications of final fuels and products, to improve and evaluate the effectiveness of processes or additives, to monitor the ageing of fuels and lubricants...The implementation of chromatographic techniques has long been mandatory to reach for the hi...

The use of chromatography in all of its forms is a powerful and widely recognized practice in petrochemical research. Due to the continuous optimization of instrumentation and columns, substantial progress in terms of separation efficiency and selectivity, speed of analysis, and sensitivity has been made over the last decades. Many petrochemical products and derivatives thereof are generally complex due to presence of a large number of compounds with varying physicochemical properties. Moreov...

This eLearning presentation by Peak Scientific will give a broad overview of gas generator technology discussing technologies used in production of hydrogen and nitrogen and pure air as well as safety and economic advantages of using generators. People attending the ELearning session will gain insight into a range of technologies used to purify nitrogen and hydrogen gas for applications such as LC-MS, GC and FT-IR, and how to select a system that will integrate with their laboratory setup...

Analytical Techniques, Methods & Laboratory Sustainability in Petroleum and Petrochemical Laboratories The demands on the analyst from the petrochemical industry continue to focus on the quest for detailed characterisation of feedstocks, intermediates and final products across the value chain in order to reduce costs and maximise productivity and ultimately profitability. In recent years there a has been a number of developments in mass spectrometry and separation science instrumentation a...
