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.

Gas monitoring instruments and systems for print factories

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Typical modern printing processes utilize solvent-based dyes. The evaporation of the dye solvents into the ambient air during the printing process may expose the workers to various chemicals. Depending on the type of solvents in case, the solvents have different long term exposure limits, which should be obeyed. Component specific measurements are necessary to protect the workers from exposure while avoiding unnecessary interruptions to the printing process from false alarms.

ASTM Color (0-7) #3070

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

Controlled Atmosphere Glove Boxes and Nitrogen Dry Boxes for Process Industry

by Systech Instruments Ltd     based in Thame, UNITED KINGDOM

Glove boxes are designed for handling both hazardous substances and atmosphere sensitive materials. For controlled atmospheres, nitrogen dry boxes provide an isolated work environment for processing samples or handling air-sensitive materials while maintaining an anaerobic or other gas specific environment within the glove box. For work with hazardous materials, glove boxes provide a leak-tight environment protecting the user from exposure to potentially dangerous materials. Glove box applications include; anaerobic testing, biological research, catalyst research, hazard material contamination and pharmaceutical packaging.

Gas monitoring instruments and systems for DeNOx process control

by Gasmet Technologies Oy     based in Helsinki, FINLAND

In most combustion process atmospheric nitrogen reacts with oxygen in high temperature conditions to produce nitrogen oxides (NOx). Total NOx production is the sum of nitrogen monoxide NO and nitrogen dioxide NO2. The emissions of these gases are controlled through setting of emission limit values (ELVs) for power plants.

Gas detection analyzers for processing ovens & dryers

by Control Instruments Corporation     based in Fairfield, NEW JERSEY (USA)

Many industries are involved in coating products with solvent-borne materials and then employing ovens or dryers to remove the solvents from the finished product. The key hazard is an explosion from the build up of solvent vapors in the oven or dryer atmosphere. This buildup could occur by a malfunction in the production process such as: a sudden or improper amount of coating, a change in ventilation controls or excessive speed. In any of these cases, the concentration of flammable vapor has an opportunity to rise above safe levels, creating a potentially explosive mixture of vapor in air.

Gas monitoring instruments and systems for process NOx measurement

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen dioxide NO2, as well as water vapor H2O, nitrous oxide N2O, carbon monoxide CO, carbon dioxide CO2 and ammonia NH3. The fixed installation products for these purposes are the Gasmet™ CEM II measurement system, and the Gasmet™ FCX Gas Analyzers, both of which utilize the FTIR measurement technique for simultaneous multicomponent analysis of the sample gas.
