    SF6 Leak Detection

    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.

    Laboratory instruments solutions for polymer and plastics industry

    Synthetic polymers and plastics are a mainstay of modern life. Because of their versatility and physical properties, plastics and polymers have conquered nearly every aspect of human activity: airplanes and cars, packaging of all kinds, medical devices and products, electronics, and countless more – without high-quality and high-tech plastics most products we use today in everyday life would look very different. Polymer production is a demanding process in which high-purity raw materials undergo complex reactions and are turned into polymers, resins, rubbers, and gums. To make sure that the products meet the specifications, the materials and processes have to be monitored along the entire production chain. This makes the use of specific and highly accurate analytical techniques indispensable. We at Metrohm are committed to providing the instrumentation and know-how you need to solve your analytical challenges in polymer analysis.

    Analytical instruments for atomic spectroscopy

    Besides Mass Spectrometry, a further variety of analysis techniques are categorized as atomic spectroscopy. Analysis techniques which use inductively coupled plasma (ICP), such as ICP-OES and ICP-MS, are among these. With increasing environmental awareness backed by regulations, an increasingly important use of atomic spectroscopy techniques is in mercury analysis. Achieving a high mass flow control performance, e.g. high repeatability or an excellent turn-down ratio, is a prerequisite to achieve a high analyzer performance. For this, a number of Axetris customers rely on our products while designing such systems.

    Analytical instruments for gas chromatography

    Gas Chromatography requires a stable repeatable flow of the carrier gas with negligible temperature drift. The Axetris MFC provides excellent control of the gas flow resulting in sharp peaks and high resolution of the chromatograms. Multiple calibrations allow the control of Helium, Hydrogen or Nitrogen. Due to the high turn down ratio of 1000:1 and more, a broad range of flows can be controlled.

    Analytical instruments for mass spectrometry

    A variety of MS techniques – such as Quadrupole MS, Time-of-Flight (TOF) MS, Ion Mobility Spectroscopy (IMS), etc. have been developed in the past decades, providing new tools for materials analyses. Flow control for mass spectrometry (MS) requires high repeatability and small temperature- and pressure dependency. This is important to achieve a high resolution and instrument resolution. Depending on the size and electrical interface requirements, the Axetris MFC modules or MFC standalone types are the ideal choices for MS applications.

    Gas analysis & monitoring system for gas purity

    The purity of a gas is an indication of the amount of other gases contained in it. A high purity refers to a low amount of other gases. High purity gas are considered to be of better quality and are generally more expensive. The purity of the gas can be expressed as a percentage or as a decimal fraction. Applications for checking the purity of the gases across different industrial sectors by air separation plants, cryogenic facilities, the quality control of industrial gases to the steel mills, etc.

  • Cloud Point of Diesel Fuel #3074

    The Cloud Point of a diesel fuel is the temperature below which wax forms giving the fuel a cloudy appearance. This parameter is an important property of the fuel since the presence of solidified waxes can clog filters and negatively impact engine performance. The traditional laboratory methods for the measurement of Cloud Point are optical in nature, but rely on cooling the fuel for the wax formation to occur. Guided Wave’s process analyzers can measure compositional changes in the fuel that will be directly related to the wax formation and hence the Cloud Point. This note will discuss the use of Guided Wave hardware and software tools for the measurement of the Cloud Point of diesel fuel using fiber optic-based, near-infrared (NIR) spectroscopy. NIR can be applied in real time directly in process.

  • Measurement solution for Perflurocarbon (PFC) emissions from aluminium industry

    The aluminium industry is the major source of perflurocarbon (PFC) emissions to the atmosphere, which are a major contributor to global warming. PFCs have greenhouse gas effects up to 10000 times that of CO2. Emissions have been reduced over the last 20 years, but further reductions are harder to achieve as all the mechanisms for PFC production are not known. In order to better understand the production of PFC on an industrial level, laboratory studies have been carried out using a small scale cell.

  • Percent Aromatics in Gasoline #3008

    The aromatic content of gasoline determines many of its combustion properties. Since it also impacts the environmental characteristics of the fuel it is desirable to have accurate measurements of this parameter. The traditional analytical method for measuring aromatics is either gas chromatography (GC) or an older method entitled fluorescent indicator adsorption (FIA), both of which are time and labor intensive. This note will discuss the use of Guided Wave hardware and software tools for the measurement of % aromatics in fuel products using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR can be applied in real time directly in process monitoring or as a laboratory procedure. In either case NIR is a time and money saving alternative to traditional methods.

  • Measurement solution for measuring total VOC via FTIR

    Current Total VOC Measurements

    The most common, and current standard, method for measuring Total Volatile Organic Compounds (VOC) is the use of a Flamed Ionisation Detector (FID). This gives a representative value of the total carbon content of a gas stream, as the FID cannot tell which specific organic compounds are present.

  • Quantitative Analysis of Steel Using Laser Induced Breakdown Spectroscopy (LIBS)

    For steel analysis, LIBS is ideal for rapid QC (quantitative analysis and detection of contaminants) for raw materials in production, and to check the elemental composition of finished products. LIBS also offers the ability to analyze slag samples that can lead to the recovery of precious metals lost in the steel production process.
