Monitoring Sulfur Hexafluoride (SF6) in the Power Utility Industry.
Monitoring Sulfur Hexafluoride in the Power Utility Industry
The SF6 Leak Detector 3434i from LumaSense offers an unmatched combination of performance and convenience. Based on the company’s Photoacoustic Spectroscopy (PAS) technology, the system offers highly accurate, reliable and stable quantitative gas analysis and detection. The growing environmental requirements and pressures regarding the use of SF6 make LumaSense’s system a coveted tool designed for everyday use. The system is able to measure the total concentration of the SF6 gas in an enclosed area, where the switchgear (or other SF6 filled equipment) is tested. Although only the total amount leaked is required by today’s standards, it is also advantageous to be able to pin point the leaks. This makes it easier to improve the integrity of the equipment. The SF6 Leak Detector system meets all of requirements for confined area such as substation Monitoring.
Positive Material Identification is a well accepted analytical materials testing and materials identification technique used within the metal alloy industry. It guarantees the materials chemical composition as required for quality control.
The research and development in the field of thin-film solar cells is an on-going process to improve efficiency even further, and to reduce manufacturing costs. X-ray fluorescence (XRF) is a field proven technology enabling users to control critical properties during development and manufacturing of the solar cells, such as elemental layer thickness and composition, improving quality and productivity, with resultant cost savings.
There is a continuing and increasing demand for a rapid, simple and cost-effective measurement of sulfur in a wide range of petroleum products including automotive, marine and aviation fuels. Benchtop EDXRF instruments such as the world renown Lab-X3500 and associated X-Supreme8000, can be found in many refinery laboratories/testing houses, with the instrument often operated by production staff on a 24/7 basis, giving accurate results conforming to globally accepted test methods, e.g. ASTM D4294, ISO20847, and the new ISO13032,etc. Both instruments used the analytical technique of Energy-Dispersive X-ray fluorescence (EDXRF) which is well regarded for its excellent performance, versatility, ease of use, speed, and cost-effectiveness.
The combustion properties of fuels are key to the efficient and safe operation of engines used in machinery and plant. One important way to measure the combustion properties of a fuel is by its hydrogen content. The measurement of hydrogen content is widely used for the characterisation of aviation fuel but with the increasing costs of all fuels and the greater incentives for fuel adulteration, this test is increasingly being adopted for non-aviation applications. Our benchtop NMR analyser MQC-23 system is widely used for the measurement of hydrogen in fuels in accordance with ASTM D7171-05.
Lubricating oils contain chemical additives that give the oil a greater in-service life. These additives contain a range of elements such as Calcium, Zinc, Phosphorus, Magnesium, Chlorine, Molybdenum etc whose concentration need to be measured as part of a quality control/assurance system to demonstrate conformance to specification.
Compliance screening and testing is often carried out during the manufacturing phase of a product, and all the way through its disposal or recycling process. It ensures that products and materials meet specific standards or comply with international and local directives or regulations. These standards and regulations are introduced to ensure the quality and safety of a product, and to minimise or eliminate its negative impact on the environment and people. Examples of products or materials tested are: electrical and electronic equipment (for compliance with the Restriction of Hazardous Substances (RoHS) directive), waste oils, soil (soil remediation depending on contents of toxic metals), children’s products (for compliance with Consumer Product Safety Improvement Act of 2008), etc.
We are playing an important role in the manufacture of HBLEDs, enabling huge changes in the global lighting industry. Our systems are used by a number of leading HBLED manufacturers providing market leading device performance and driving down cost of ownership. They are also used in the manufacture of other light emitting technologies e.g. OLEDs providing process solutions from R&D to full scale production.
Low field Nuclear Magnetic Resonance (NMR) is routinely used in core analysis laboratories to examine the T2 relaxation time distribution of fluids in core plugs. These distributions can be interpreted to give information on: pore size distributions; permeability; total and effective porosity; free fluid index and bound water volumes. The partnership between Oxford Instruments and Green Imaging Technologies allows us to integrate hardware and software to enable any core analysis laboratory to generate these petrophysical results without the need for in-depth knowledge of NMR.
OmniAire HEPA air filtration machines can remove odors and toxic VOCs released into the air during the cleaning and removal process. OmniAire portable air filtration and purification equipment offers the most efficient and economical solution to reduce toxicity and improve safely for your Bio-Hazard projects. Typically, the standard 99.97% HEPA filter is sufficient, however, if you need the next level of airborne pollutant removal for more toxic applications, such as filtering out VOCs, viruses, smoke and gas molecules, add an OdorGuard Activated Carbon filter.
Containment and safety issues are a critical consideration when working on any mold, asbestos, or lead remediation/abatement projects. Improperly contained, the dust and bio-contaminants released can, be very harmful for both on-site workers and occupants in neighboring areas. Exactly how you approach your containment and capture solutions will depend on the individual site’s risk assessment report. If you need help identifying solutions to the issues raised in the report, feel free to contact our customer service department and we can review your options together. In most cases, however, there are four common considerations that will be relevant:
-Meeting Containment and Air Change Requirements
-Monitoring of Containment Pressure
-Sterilization of Filtered Air
-Removal of Odors, Mold Spores, VOC’s and other Airborne Bio-Contaminates
Industry standard best practices are designed to ensure that all work done on Asbestos Abatement Projects is done to the highest level of safety and risk management. Containment of the generated waste water fibers and debris is critical to proper compliance and worker safety. If these fibers are not captured and contained, they can be very harmful for the environment, on-site workers and the occupants of neighboring areas. Exactly how you approach your containment and capture solutions will depend on the individual site’s risk assessment report. If you need help identifying solutions to the issues raised in the report, feel free to contact our customer service department and we can review your options together.
Water from showers at Asbestos Abatement sites is often contaminated with asbestos fibers from washing protective gear and equipment. This water must be filtered prior to discharge into a drain.
Anywhere there is a large gathering of people, respiratory infections can be acquired due to exposure to airborne pathogenic microorganisms. To help prevent the spread of diseases the Center for Disease Control (CDC) recommends that potential problem areas be isolated and the air purified by portable, HEPA air filtration equipment. OmniAire and OmniAire PAC portable HEPA air filtration machines provide a clean air supply necessary to protect the public in gathering areas such as schools, emergency shelters or temporary healthcare facilities. To comply with CDC guidelines to prevent the spread of disease and contamination of sensitive areas, OmniAire HEPA air filtration machines are commonly used to:
-Create a negative air pressure in isolation containment
-Supply purified air for required air changes (ACH)
-Sanitize airflow in operating and patient’s rooms
-Purify air in waiting rooms and public areas
-Prevent contamination in compounding pharmacies
In the electronics industry, Energy dispersive X-ray Fluorescence (EDXRF) analysers are used to both identify the content and measure the thickness of metallic coatings on electrical and electronic components from printed circuit boards to connectors.
