Precision, accuracy and robustness are key words and essential parameters to determine the effectiveness of any analytical application. Surveyors, refinery, and QC labs must determine the Nitrogen and Sulfur content with fewer personnel while the number of samples keep increasing and the time to report is under pressure. Moreover, all these analyses must be done in compliance with a variety of test methods, such as the ASTM D5453, ASTMD4629 and ASTM D6667. All these factors are pressing on...

Volatile organics like naphtha are amongst the most challenging samples to be analyzed by ICP techniques. Wealth of emission lines originating from the organic matrix and high volatility demonstrate challenges for ICP-OES analyzers. A robust plasma as well as an optical system with high spectral resolution are required in order to routinely quantify trace elements in the low µg/kg range. For specification analysis in the low µg/kg range ICP-MS often is the method of choice as conventiona...

This paper presents a tunable laser analyzer that has the capability to analyze several components in a gas sample stream. More specifically, a multi-gas system for simultaneous detection of C1-iC5 hydrocarbons, using a room temperature distributed feedback (DFB) inter-band cascade laser (ICL) array, emitting in the 3.3-micron band has been realized. It combines all the advantages of the tunable laser spectroscopy method for a fast, sensitive and selective in-line multicomponent tunable laser...

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...
