Karl Fischer titration is an analytical technique widely used by chemists throughout the petroleum related sector.  Many chemists will agree that accurate results are most important followed by delivering results quickly, consistently and safely.  Smooth transitions between testing runs is also highly desirable. There are a number different KF methods available to cover the spectrum of samples within the hydrocarbon markets.  This webinar will give insights into which methods are best e...

Vacuum ultraviolet absorption spectroscopic detection for gas chromatography (GC-VUV) was introduced in 2014. Since then, it has been established as a complementary tool to traditional gas chromatography - mass spectrometry (GC-MS) for qualitative and quantitative analysis. GC-VUV is based on the absorption detection of volatile and semi-volatile species from 120 - 240 nm, where all chemical compounds absorb and have unique absorption signatures. GC-VUV excels in the differentiation of isomer...

In recent years, comprehensive two-dimensional gas chromatography, or GCxGC, has become widely implemented in the chemical industry. This is due in part to the fact that GCxGC affords increased peak capacity, improved peak resolution, and up to an order-of-magnitude increase in sensitivity compared to traditional one-dimensional GC. Other highly influential factors include the availability of robust commercial systems with options for flow or cryogenic modulation and the development of enhanc...

In ethylene steam cracker facilities, ionic fouling, radical fouling and Diels-Alder fouling occur leading to the formation of solid materials depositing onto equipment. This subsequently hinders heat exchange within the plant resulting in costs in the range of millions of euros. The identification of these residues and quantification of their constituents is considerably challenging due to their very high complexity. The value of evolved gas analysis techniques (EGA) for polymer and chemi...

Gas chromatography (GC), mass spectrometry and optical spectroscopy are standard techniques for the analysis of petrochemical matrices and within last decade also comprehensive two-dimensional gas chromatography (GCxGC) did become a key technology in this field. The application of GC and GCxGC in hyphenation with mass spectrometry as well as spectroscopic techniques allow unprecedented qualitative as well as quantitative investigation of these matrices. However, the analysis of high boiling m...

Fingerprinting techniques using stable isotopes in formation-waters have been developed that overcome many of the problems with previous source-identification methods. Over the past 20 years, isotope fingerprinting techniques have been used repeatedly by the oil industry in Western Canada and abroad in a wide variety of exploration and production operations including for: Drill-Stem-Testing; completion operations; production monitoring; waterflood monitoring; stray-fluid identification during...

In chemical and petrochemical laboratories gas chromatography (GC) is a commonly used analysis technique. However, as matrices are challenging, the regular “out of the box” configurations of GC instrumentation may not be sufficient to overcome the application challenges caused by these matrices. Therefore often customized GC instrumentation, configured with additional detectors, valves, temperature control zones and sample introduction devices, is used. Using this customized instrumentati...

Combustion ion chromatography (CIC) provides a powerful means of measuring halides in a variety of samples. This webinar will cover the theory and application of CIC. A classic application of CIC in refining – the determination of halide in liquefied petroleum gas (LPG) – will be highlighted. Additional applications will cover gaseous, liquid, and solid sample types. Problems CIC helps solve include corrosion, product purity, catalyst poisoning, and material composition. The webinar not o...

ASTM D7900:  Boiling Point Distribution from C1 to C100 Boiling Point Distribution of Crude Oil with Speciation of Biomarkers to Phytane, on One Gas Chromatograph (GC) The accuracy of the boiling point distribution by method ASTM D7169 is compromised by solvent interference/quenching in the C4 to C8 boiling point range.  The new “merge” method, ASTM D7900, does a good job of providing enhanced accuracy to the boiling point distribution;  however, D7900 requires two analyses on two g...

Measurement of bulk composition of hydrocarbon groups and individual compounds in automotive spark-ignition fuels is important for quality control as well as ensuring compliance with various governmental regulations. As such, multiple ASTM methods exist for measuring various aspects of automotive fuel samples. Most of the methods are limited in scope to a subset of hydrocarbon groups or specific compounds of interest, meaning that multiple methods are required for typical production control...

The petroleum and petrochemical industry is highly regulated and the vast majority on analysis is carried out using industry standard methods such as those published by ASTM, DIN or the Energy Institute. These methods are also used to check for product quality excursions when field issues are encountered but in many cases more sophisticated techniques are required. This presentation will describe approaches to problem solving field issues using flexible hyphenated chromatographic and mass spe...
