Analyzing moisture, and how much of it, is critical to the performance of petroleum products, as well as infrastructure and product integrity. One of the most famous methods for moisture analysis is Karl Fischer Titration (KFT). KFT has a wide dynamic range, and is easy measurement, but has difficulty in measuring relatively low amounts of moisture. This time, we have developed the new trace moisture analysis system using Gas Chromatography with the Novel BID. In this work, we introduce the h...

Over the past 20 years, advances in modern ultra-high resolution mass spectrometry have forever changed the expectations of petroleum analyses. Facilitated by advances in ionization methods (that enable molecular-level analysis irrespective of initial or final boiling point), ultra-high resolution Fourier Transform Ion Cyclotron Resonance mass spectrometry (FT-ICR MS) routinely resolves and identifies tens-of-thousands of species (at the level of elemental composition assignment) in individua...

OFCEAS or Optical Feedback Cavity Enhanced Absorption Spectroscopy, is a gas analysis technology developed by the University Joseph Fourier. OFCEAS essentially differs from the older technology enhanced-cavity TDLAS by its feedback principle: a part of the emitted radiation is returned from the chamber to the laser, enabling the tuning of the laser and the cavity, creating a resonance phenomenon. The measuring cavity in which the sample is analyzed is equipped with high reflectivity mirrors (...

Phosphorous, sulfur and chlorine are commonly analyzed elements in liquids such as petroleum products and organic solvents. For example, phosphorous is added to lubricating oils to prevent wear of gears under high pressure. Sulfur content in automotive fuel oils are regulated by the US environmental protection agency (EPA) and directives such as EURO VI to minimize air pollution due to automotive vehicles. Chlorine, contained for example in crude oil, is an unwanted element known for corrodin...

Being a founding member of the Allotrope Foundation - granted the 2017 Bio-IT World Best Practice Award in Knowledge Management - Bayer is implementing strategically the Allotrope Framework to escort scientific data throughout its complete lifecycle from method development over acquisition, processing, reporting, archiving to submission, using a common set of standard tools. Allotrope aims to make the intelligent analytical laboratory a reality – an automated laboratory where data, methods...

Oil industry started long before 1900 and is older than gas chromatography, so test distillation was used for sample analysis and not GC. Fast GC analysis of Diesel and Jetfuel already is a standard but Gasoline is not. Detailed hydrocarbon analysis (DHA) with pattern recognition uses GC analysis input to separate and identify gasoline and blendfeed compounds in 6 minutes. The composite report of DHA is input for the fugacity filmmodel of ASTM method D86 distillation. GC post-run software all...

Comprehensive two-dimensional gas chromatography (GCxGC) has been proven to be an ideal platform for the analysis of complex mixtures, but the data processing aspect has a reputation as being difficult and time-consuming. GCxGC data exploration, filtering and mining need not be complex, and can be implemented in an environment that is based on classical peak detection algorithms and chromatographic rules. Here we will demonstrate simple yet effective GCxGC data processing for a range of...

Fugitive hydrocarbon emissions cost the energy sector $5B per year, account for 12% of greenhouse gas emissions and jeopardize safety and public health. Current gas monitoring methods lack the ability to take measurements in moderate winds, at varying heights and to provide simultaneous measurements of a diverse range of hydrocarbon species. The most advanced technique for remote emission measurements is differential absorption lidar (DIAL), in which intense IR pulses are fired into the atmos...

Ultrahigh performance supercritical fluid chromatography (UHPSFC) coupled with mass spectrometry (MS) provides an agile and robust analytical platform to meet the challenge of analysis of complex petrochemical material. The selectivity afforded by the different SFC column technologies, mobiles phase and atmospheric pressure ionisation techniques provides approaches to reveal specific chemistries within the sample, with the added benefit of sample compatibility with the solvents used. The tech...
