Measurement solution for measuring total VOC via FTIR

by Protea Limited     based in Middlewich, UNITED KINGDOM

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.

Percent Aromatics in Gasoline #3008

by Guided Wave Inc,     based in Rancho Cordova, CALIFORNIA (USA)

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.

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

by Applied Spectra, Inc.     based in Fremont, CALIFORNIA (USA)

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.

Octane Number of Gasoline using NIR Spectroscopy #3012

The measurement of the octane number of gasoline using NIR spectroscopy is both fast and reliable utilizing Guided Wave analyzers. Results are available in real-time (seconds) for multiple parameters in complex streams. Request Application Note #3012

Cetane Number of Diesel Fuels #3010

by Guided Wave Inc,     based in Rancho Cordova, CALIFORNIA (USA)

The Cetane number of a diesel fuel is a measure of the ignition properties and is an important specification that must be met during fuel production. The traditional laboratory method for Cetane number determination is the knock engine method in which the fuel is burned and its combustion characteristics compared to known standards. This method is time and labor intensive, and provides no ability for real time control of production. This note discusses the use of Guided Wave hardware and software tools for the measurement of Cetane number in diesel fuel using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR is 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.

SF6 Leak Detection

by LumaSense Technologies, Inc.     based in Santa Clara, CALIFORNIA (USA)

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.

Hydroxyl Number in Polyols (OH#) #3013

by Guided Wave Inc,     based in Rancho Cordova, CALIFORNIA (USA)

The use of polymeric polyols is commonplace in the manufacturing of polyurethanes and other specialty polymers. The hydroxyl number (OH#) is a measure of the concentration of the hydroxyl groups on the polyol. This is an important parameter to monitor and control during polyol production. The laboratory method that is commonplace for hydroxyl number determination is both time consuming and involves the use of hazardous materials. This note will discuss the use of Guided Wave hardware and software tools for the measurement of hydroxyl number in polyols using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR can be applied in real time directly in process or as a laboratory procedure. In either case NIR is a time and money saving alternative to traditional methods. NIR also offers the benefit of increased safety over traditional methods. For well established process measurements, a Guided Wave ClearView® db multi-wavelength photometer can be used to achieve similar results.

Measurement solution for FTIR Vs. GC in gas analysis

by Protea Limited     based in Middlewich, UNITED KINGDOM

Comparison of Technologies

A gas chromatograph (GC) has traditionally been the technology of choice for laboratory analysis of gas samples. GCs have been used for over 50 years in the qualification and quantification of complex mixtures of gases. The techniques and methodology required to run GCs are often a pre-requisite for any laboratory technician. Recent developments in Fourier Transform Infra-Red (FTIR) gas analysis has enabled this technology to start to replace GCs in the lab.
