  • The World’s Largest Gas to Liquids Facility Runs on Thermo Scientific SampleManager LIMS

    Established by Shell and Qatar Petroleum in 2006, Pearl GTL is the largest gas to liquids facility on the planet. Gas to liquids (GTL) is the conversion of natural gas to liquid fuels and other products, including gasoil, naphtha, kerosene, normal-paraffin and lubricants. Pearl GTL has a capacity of 140,000 barrels per day of these products and 120,000 barrels per day of liquefied petroleum gas, ...

  • QuadOa and OGI: how EPA regulations are changing the way we look at gas leaks

    Earlier this year, the Environmental Protection Agency (EPA) published Regulation 40 CFR, Part 60, Sub-part OOOOa, commonly known as Quad Oa, and finally brought optical gas imaging (OGI) firmly into the mainstream. This presents a major shift in the way fugitive emissions are regulated, and the technology that can be used.  Detecting and acting on gas leaks is naturally a major ...

  • Converting your GC carrier gas from helium to hydrogen : A step by step guide

    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, ...

  • Cost Containment: Beyond the Obvious

    Utilities today can implement a number of different initiatives to help them contain costs and maximize profits. Some of those, such as switching to a more efficient fuel source if possible, can produce obvious results that are relatively easy to calculate. But there are other initiatives, though less obvious, that can produce significant results at the bottom line. One such cost-containment ...

  • Field Detection of Chlorinated Alkenes in Well Water using the FROG-4000 Portable GC - Case Study

    Introduction Defiant’s FROG 4000, a portable GCPID system, was used to identify and determine the concentration of chlorinated alkenes in several extraction wells located in Tacoma Washington. Split samples were taken at each well and sent to an offsite lab for analysis. This case study examines the field exercise and highlights the high degree of agreement between the offsite lab and ...

  • Comparison of Impinger and Canister Methods for the Determination of Siloxanes in Air

    Abstract Tliis paper compares canister and impinger methods for the analysis of siloxanes in air by gas chromatography/inass spectrometry (GC/MS). Siloxanes are frequently found in commercial and consume? products such as detergents and cosmetics. Most low molecular weight siloxane compounds volatize quickly into the atmosphere; however, some end up in wastewater or landfills when consumer ...

  • Avoiding Sewer Fires with Vapor Space Organics Monitoring

    ABSTRACTRegulation of flammable gases released from wastewater discharges is facilitated by the use of the Vapor Space Organics test method. Such regulation can reduce the risk of a flash sewer fire, resulting damage and potential injury. The updated 2003 VSO process developed by Severn Trent Laboratories produced data that was equivalent to the 1990 VSO process developed and used by the ...

  • Making a TO-15 Working Standard and the Super Standard Calculator – V2.01

    We already learned how to calibrate our TO-15 system, what our concentration units mean, and how to properly read our vacuum gauge while pressurizing samples. We are clearly going out of order here, because I have never covered how to prepare a working standard (necessary for ...

  • Determination of micro and macro elements in waters with the ELAN DRC-e

    The ability of reaction cell technology to reduce the effects of spectral interferences is well-known, but another, lesser-known capability also exists: extending the dynamic range. This is accomplished by adjusting the bandpass parameters with no gas in the cell. Because the bandpass parameters can be adjusted on a per-mass basis, sensitivity can be reduced on selected isotopes without affecting ...

  • Analysis of Pesticides in Baby Foods Using a GCMS-TQ8030 GC/MS/MS, Part II

    Contamination of food products with pesticides is a growing concern because of recognized adverse health effects, increasing world-wide usage of pesticides, and increasing imports of raw foodstuffs from foreign sources. The concern is particularly acute for baby foods because of the high vulnerability of babies to health effects from synthetic chemicals such as pesticides. Gas chromatography ...

  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...
