Lead (Pb) on Surfaces by a Portable X-Ray Fluorescence (XRF) Analyzer
This surface sampling method was developed to provide a reliable, portable procedure that will provide prompt measurement of surface contamination levels of lead. Information gained from samples taken during an initial walk-through portion of an inspection may influence decisions regarding the next steps to take, making the inspection more productive. Immediate clearance of clean areas such ...

On-site elemental analysis of drywall with the Thermo Scientific Niton XL3t series XRF analyzer
Application Reports of headaches, nosebleeds, central nervous system disorders, and other serious health effects have been reported from those exposed to compounds emitted from Chinese drywall (CDW). Additionally, surface corrosion of metal objects, including jewelry, decorative plumbing fixtures, HVAC coils, and electrical wires have resulted in cosmetic and mechanical damages. These damages can ...

Portable Infrared Analyzers Provide On-Site Measurement of Oil and Grease Levels in Hydraulic Fracturing Water
The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off-site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water. Waiting for remote laboratory results to determine the oil level can take several days to a ...

Accurately Measure Hydrocarbon (Oil/Grease) Levels in Produced Water in Under 15 Minutes
Determining total hydrocarbon or oil/grease levels to ensure compliance with regulatory permit requirements for discharging produced water is a worldwide problem facing the oil and gas industry. Ensuring compliance with these regulations and avoiding fines for non-compliant discharges requires more frequent wastewater measurements to determine the total hydrocarbon concentration. The portable ...

Comply with Highly Regulated Oil in Water Measurements Using Portable Infrared Analyzers
The Petroleum Industry – both offshore and onshore -- has regulations that limit the amount of oil in discharged water. Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on drilling platforms for over 45 years for a number of reasons. On oil rigs where real estate is at a premium, infrared analyzers such as the Wilks InfraCal TOG/TPH Analyzers are ...

Method X: Determination of metal concentrations in emissions from stationary sources (instrumental analyzer procedure) case study
Method X is an instrumental analyzer procedure for the determination of multiple metals using x-ray fluorescence as an analytical technique. Method X specifies the criteria for accuracy stability and precision that must be met by an x-ray fluorescence based instrument analyzer. Method X also describes the emission test procedures associated with an x-ray fluorescence based metals measurement ...

Different technology options for monitoring oil in produced water – inline continuous monitoring and IR analysis
No offshore facility wants to be caught with a sheen around their platform as that can result in a costly fine for exceeding discharge permit limits for oil. Onboard oil in water analyzers are necessary to ensure the oil/water separation systems are functioning properly before overboard disposal of the produced water. Bench top analyzers have traditionally been used to test oil in water although ...

Portable IR Analyzers Provide Petroleum & Wastewater Industries with Accurate Oil Content Measurements
Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on off-shore and on-shore drilling platforms for well over 45 years. U.S. EPA methods 418.1 and 413.2 were used extensively on a worldwide basis until the Montreal Protocol called for Freon (the solvent used in the analysis) to be phased out. Infrared analysis using tetrachloroethylene (perchloroethylene) is ...

Comparing TGA, FTIR and fixed filter infrared analyzers for measuring soot levels in in-service lubricants
Measuring soot in diesel engine oil has become more important as soot levels get higher due to exhaust gas recirculation. As soot isone of the key indicators for the condition of the oil, diesel engine maintenance programs performing regular soot checks can realize cost savings by extending drain periods and reducing used oil disposal. TGA (Thermal Gravimetric Analysis) is the traditional method ...

Solvent choices for infrared testing of oil and grease in water
Water is a very strong absorber in the mi d infrared (I R) regio n where o il is measured. We see the effect of infrared absorbance when a cold bucket of water left in the sun is quite warm by afternoon due to the absorption of infrared energy as heat. When measuring part per million (ppm) oil levels with mid IR, the water absorbs so much of the infrared energy that the signal becomes saturated ...

What the Wastewater Industry can learn from the Petroleum Industry when it comes to measuring oil in water
I recently read a comment in the Steve Jobs biography by Walter Isaacson that different divisions within a company do just what the name implies—divide a business. Integration across and communication between the departments was essential to smooth functioning product. I think the same is true in the analytical analysis/measurement world—there seems to be a divide in communication ...

New White Paper features Solvents for Oil and Grease in Water Measurements
A White Paper entitled, “Solvent Choices for Infrared Testing of Oil and Grease in Water” was recently published by Wilks Enterprise, Inc. Infrared (IR) analysis is widely used worldwide for determining the amount of oil and grease in water as it is a cost-effective measurement technique that can be easily done on-site or in a laboratory. Since water is a strong absorber in the ...

In-House Oil Analysis Lab Saves Gold Mine Millions in Downtime, Repair and Replacement Costs
A low-grade surface mining operation depends upon huge and expensive equipment such as Hitachi 5500 shovels and Caterpillar 793 haul trucks. Oil analysis is essential to identify problems so they can be corrected before they cause equipment to go down for major repairs. In the past, a multinational mining firm sent samples to an outside lab for analysis but the cost of this approach limited the ...

New ASTM Test Method Offers Quick and Easy Oil and Grease Measurement for Water and Soil Samples
Onsite Field Measurement of Oil and Grease A quick and easy field analysis method for determining oil and grease concentration levels is important for both offshore oil platforms and soil remediation sites.. Prior to the Montreal Protocol, infrared (IR) analysis using Freon as an extraction solvent was a widely used field and laboratory method. In 1999, the U.S. EPA promulgated Method 1664A to ...

City of Houston Total Organic Carbon - Case Study
ABSTRACT The City of Houston, Texas has been aware of the implications that current and pending regulatory standards would have on the operation of their four surface water treatment facilities. In particular, the City has closely monitored changes in regulations related to enhanced coagulation, total organic carbon (TOC) removal, and disinfection by-products (DBP) reduction. The City has, and ...

Sulfur Compounds Analyzer MEXA-1170SX
The MEXA-1170SX is a continuous gas analyzer for sulfur compounds existing in engine emissions. It can measure SO2 concentration and the amount of total reduced sulfur compounds (TRS), such as H2S, separately. It can also measure the total sulfur compounds (TS) that contains both gaseous compounds and liquid compounds in PM, such as SO3. By utilizing ultra-violet fluorescence (UVF) method and ...
