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...

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...

Chemical fingerprinting of crude oils: Gaining an extra dimension from GCxGC -TOF MS The enhanced separation offered by comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCxGC-TOF MS) has made the technique a popular choice for petrochemical analyses. Intelligent GC Solutions based on Capillary Flow Technology The complexity of petrochemical fractions have challenged analytical scientists to this present day. In hydrocarbon processing, dedicated...

A novel fast response, low level gas analyzer system for detection of of SO2 and CO2, based on combined NDIR- and NDUV-technology Fast response gas detection is required for particular applications in the field of elemental analyzer (Sulfur and Carbon). In this application solid samples (e.g. steel, ores, finished metals and other inorganic materials) where typically combust by means of a RF-furnace. During the combustion the gas concentration (SO2 and CO2) is measured in the exhaust with...

Part 1 - Coupling Ion chromatography to mass spectrometry Ion chromatography (IC) is routinely used for ion analysis, typically with non-specific detectors such as conductivity or UV/Vis. Interest in utilising IC with mass spectrometry (MS) detection has increased in recent years in order to reduce interference, improve sensitivity and increase confidence in compound identification. This webinar aims to explain the different approaches that can be used to couple IC to MS demonstrated with...

The performance and benefits of supercritical fluid chromatography (SFC) have been recognized already for decades. Due to the introduction of the latest generations of SFC systems, instrument robustness as well as system suitability testing are expected to soon reach the same levels of gas chromatography (GC) and high performance liquid chromatography (HPLC). Consequently, the technology has regained increased interest for a variety of applications in a wide range of industries.  From a...
