Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous in the environment. They belong to a group known as persistent organic pollutants (POPs). Monitoring is important because they are identified as carcinogens. Multiple isomers exist, which are difficult to resolve chromatographically. SLB®-ILPAH is a special purpose column based on an ionic liquid stationary phase. A distinct combination of stationary phase selectivity and efficient column dimensions allow exceptional resolution of PAHs, including several isomer sets.

  • The effect of draw out lens diameter on sensitivity of GC–MS analysis

    Gas chromatography–mass spectrometry (GC–MS) allows isolation and identification of individual analytes within a complex mixture. Helium has traditionally been the first-choice carrier gas, owing to its inertness, performance, and relatively cheap price. Since 2001, however, helium has become increasingly expensive with a reported global increase in price of 500% between 2001 and 2016 (1). In 2012–2013, the global helium shortage increased the number of GC users switching to alternative carrier...

  • Tips for Refinery Gas Analysis

    Refinery gas analysis (RGA) is an important application in oil and gas which characterizes the gases produced during crude oil refining, including stack emission, flame and reformate streams. The challenge in RGA analysis is the reliable analysis of variable sources and compositions of gases produced via fluid catalytic cracking (FCC). The analysis must be quick and accurate to allow engineers to monitor permanent gases, such as hydrogen, oxygen, nitrogen, carbon monoxide and carbon dioxide, saturated and...

    Monitoring of methane and Non-Methane Total Hydrocarbons (NMTHC) is an important tool for process monitoring. In the microelectronics industry, the silicon substrates (wafers) are stored in containers, named FOUP (Front Opening Unified Pod) made in polymers (PC, PEEK, COP, PEI). Such materials are able to adsorb the Volatile Molecular Contaminants (VMC) and subsequently outgas these ones in presence of wafers, leading then to defective wafers. Depending on the process, the composition of the gas in the FOUP can...

    Learn how to convert your GC carrier gas from helium to hydrogen with this step by step guide. With recent increases in helium pricing and an increasing number of regulated methods allowing the use of hydrogen as a carrier gas for GC, more labs are looking to switch to alternative carrier gases. This step by step guide will provide you with the necessary information to convert your GC’s carrier gas supply from helium to hydrogen. Hydrogen produced by a gas generator offers a safe, consistent and reliable...
