The gas generators for calibration based on the use of “Method of Permeation Tubes.”. The permeation tubes are sealed capsules containing a small amount of the component that is in contact with a permeable membrane stable. The permeation through the membrane produces a vapor of the compound of the component of small quantity, very stable as a stream in time. This permeate stream by mixing with a dilution gas controlled and precise (for example nitrogen) creates a mixture in track at the desired...

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.

Raw gases are untreated flue gases that have not passed through an emissions control technology system like selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR). They are generally measured for the sakes of process control and warranty tracking. Typically only a few components are measured but fourier transform infrared spectroscopy FTIR technology allows the measurement of all components.

Sea cargo containers and wooden packing materials are fumigated to control the spreading of pest animals and micro-organisms. Fumigant gases are toxic and measurements are carried out as a health and safety precaution. Measurements are required by e.g. customs inspectors prior to opening containers, making the shipping companies responsible for carrying out measurements. Products shipped in containers may release VOCs from e.g. solvents and glues used in manufacturing process. The concentrations of vapors may be...

In the semiconductor manufacturing industry, various perfluorinated compounds (PFCs) are used. The emissions of the PFC compounds into the ambient air are reduced by scrubbing of the exhaust gases from the process. In this process, the Gasmet™ FTIR Gas Analyzers can be used to measure the emissions into the atmosphere and also monitor the efficiency of the scrubbers. Typically monitored PFCs in the exhaust gas include carbon tetrafluoride CF4, trifluoromethane CHF3, and hexafluoroethane C2F6.

Several EU directives and national laws in European countries set requirements for continuous monitoring of flue gas emissions at power plants. Further requirements are set on the quality assurance of the installed measurement systems at the plants. The relevant standard in this regard is EN 14181:2004, the quality assurance of automated measuring systems. The standard dictates how to determine that the measurement systems installed for continuous emissions monitoring at a plant operate according to the directives...

The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevoflurane,...

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.

Modern production method of nitric acid production may lead to generation of several different gaseous emission components, such as nitrogen oxides (NOx), ammonia NH3 and nitrous oxide N2O. Nitrogen monoxide is an intermediate gaseous product in manufacturing of nitric acid HNO3. NO is formed in a catalytic reaction between ammonia and molecular oxygen O2. But undesirable side reactions may result in formation of nitrogen dioxide NO2 and nitrous oxide N2O. The NO and NO2 emissions can be reduced by use of Selective...

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...

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.
